At TMP Inflatables, we’ve helped experiential marketing agencies and brands deliver unforgettable campaigns since 2004. We design inflatables for maximum visibility, durability, and impact, but even the toughest builds need proper cleaning and storage if you want them looking sharp event after event. If you’re in need of high-quality inflatables, feel free to get a quote from us.
This guide will walk you through a simple, repeatable system to clean and store inflatables the right way, without mold, weird smells, sticky surfaces, or surprise stains.
Why inflatables get moldy (even when they “feel dry”)
Mold needs three things:
- Moisture (even a little)
- Warmth
- Organic material (dirt, skin oils, spilled drinks, grass residue, etc.)
Inflatables are basically big surfaces that love to trap moisture in all the sneaky places:
- Seams and stitching lines
- Velcro strips, zippers, and attachment points
- Inside folds where air can’t circulate
- Bases that sat on wet grass
- Areas touched by lots of hands (oils plus dirt equals “mold food”)
Even if the top looks dry, a slightly damp seam can turn into a mold patch after a few weeks in storage.
The “no mold” rule: clean, rinse, dry, then dry again
If you only remember one thing: dry time matters more than wash time.
A quick wipe-down helps, but mold prevention comes from:
- Removing grime (so mold has less to feed on)
- Fully drying the material (especially seams and folds)
- Storing it where moisture cannot get trapped
What you’ll need (simple kit) how to clean inflatables
You don’t need fancy chemicals. You need consistency and the right tools.
Basic cleaning supplies for how to clean inflatables
- Mild soap (dish soap works)
- Soft microfiber cloths (several)
- Soft-bristle brush (for textured spots)
- Two buckets (wash + rinse)
- Spray bottle (optional, makes it faster)
- Clean towels
Drying and storage tools for how to clean inflatables
- Floor fan or air mover (highly recommended)
- Dehumidifier (great for warehouses and basements)
- A clean tarp or drop cloth (for staging)
- Storage bags or heavy-duty breathable covers
- Desiccant packs (silica gel) for bins or bags
- Labels (painter’s tape + marker works)
What to avoid on how to clean inflatables
- Bleach (can weaken coatings and discolor print)

How To Clean Inflatables Step 1: Do a quick pre-check before cleaning
Before you start scrubbing, take 3 minutes to inspect and document.
What to look for
- Dirt lines along the base (grass, dust, street grime)
- Sticky spots (soda, sunscreen, spilled drinks)
- Bird droppings (common at outdoor events)
- Mud splatter
- Any small tears, loose stitching, or scuffs
- Mildew smell (even if you don’t see it yet)
Pro tip on how to clean inflatables
Snap a few photos on your phone before cleaning. If you’re managing multiple inflatables for a roadshow or agency client, this makes it way easier to track condition and maintenance.
How To Clean Inflatables Step 2: Dry-clean first (yes, before water)
This is the step people skip, and it matters.
What to do
- Sweep or shake off loose dirt and debris
- Use a dry microfiber cloth to remove dust
- Lightly brush textured areas to loosen grime
If you go straight to wet cleaning, you can turn dust into muddy streaks and push dirt deeper into seams.
How To Clean Inflatables Step 3: Spot clean stains the smart way
You don’t always need to wash the entire inflatable. Often, you just need to spot-clean high-contact zones:
- Entry points
- Bases and anchor zones
- Handles
- Areas near fans/blowers
- Any spot touched by crowds
Simple spot-clean mix
- Warm water + a few drops of mild dish soap
Dampen the cloth (don’t soak it), wipe gently, then wipe again with clean water on a second cloth.
For more stubborn stains, consider using some of these 6 solutions that have proven effective in various cleaning scenarios.
Lastly, be cautious about moisture during the cleaning process. Excessive moisture can lead to mold growth. For more information on how mold and moisture interact, refer to this resource.
Sticky residue (soda, sunscreen, tape adhesive)
- Warm soapy water first
- If it’s still stubborn, try a tiny amount of white vinegar diluted 1:5 with water on a test area first
If the inflatable is heavily printed and you’re unsure, test in a hidden spot first. Print quality is tough, but it’s not worth risking a large visible fade.
How To Clean Inflatables Step 4: Full wash (for big event grime)
If your inflatable was used outdoors, handled by a crowd, or stored without a cover, do a full wipe-down.
Best method: wipe, don’t soak
- Lay the inflatable on a clean tarp
- Use a cloth or soft brush with warm soapy water
- Work in sections from top to bottom
- Change water if it turns dirty
- Rinse by wiping with clean water (separate cloth)
The goal is to clean the surface without pushing water deep into seams.
Don’t forget the base
The base is where moisture + dirt hang out the most. Take your time here.

How To Clean Inflatables Step 5: If you find mold or mildew, don’t panic (but act fast)
If you see black dots, fuzzy patches, or you smell mildew, you need to treat it properly.
First, safety
- Wear gloves
- Consider a mask if the mold is visible/heavy
- Do this in a ventilated area
Mild mildew treatment (gentle approach)
- Mix: 1 part white vinegar + 5 parts water
- Lightly dampen a cloth and wipe the affected area
- Let it sit for 10 minutes
- Wipe again with clean water
- Dry thoroughly (more on that below)
Why not bleach?
Bleach can damage coatings, weaken seams, and ruin colored print. It can also “appear” to remove mold by whitening, while leaving spores behind.
If mold keeps coming back
That usually means it’s inside folds, seams, or the inflatable wasn’t fully dried before storage. At that point, a deeper clean and longer dry cycle is required.
If you’re working with high-value custom builds for brand activations, it may be worth contacting your supplier for material-safe recommendations. If your inflatable was produced by TMP Inflatables, you can reach us at hello@tmpinflatables.com and we’ll point you in the right direction.

How To Clean Inflatables Step 6: Drying is the whole game (do this like a pro)
You can clean perfectly and still get mold if you dry poorly.
The right drying sequence
- Towel dry obvious wet areas
- Air dry open and flat as much as possible
- Force airflow across seams, bases, and folds using fans
- Wait longer than you think
- Do a final touch test before packing
What “dry” actually means
Not “feels dry on top.” It means:
- Seams are dry
- Underlapping flaps are dry
- The base is dry
- Any Velcro strips are dry
- The inside surface (where folds touch) is dry
Quick test that works
Press a clean, dry paper towel into a seam and hold for 10 seconds. If it picks up moisture, you’re not ready to pack.
Ideal environment
- Low humidity
- Good ventilation
- Fans running across the surface
- Dehumidifier if you’re indoors and it’s humid

How To Clean Inflatables Step 7: Packing without trapping moisture
This is where mold gets “locked in.”
How To Clean Inflatables Golden rules
- Never pack warm and damp after a sunny day without extra drying time
- Don’t roll it tighter than necessary
- Avoid sealing it in airtight plastic if you’re not 100 percent confident it’s dry
How To Clean Inflatables Folding tips (that also protect print)
- Fold printed faces inward when possible
- Avoid sharp creases on the same line every time
- Vary your fold pattern between events
- Keep zippers and Velcro from rubbing print surfaces
If your inflatable includes removable pieces (like banners, attachments, or internal supports), pack them separately so moisture doesn’t get trapped where materials overlap.
How To Clean Inflatables Step 8: Choose the right storage container (breathable beats “sealed”)
A lot of people assume airtight storage is “safer.” With inflatables, it can backfire. Airtight containers trap humidity if the inflatable wasn’t perfectly dry.
Best options for How To Clean Inflatables
- Heavy-duty storage bag with some breathability
- A tough transport bag designed for event gear
- Clean bins with desiccant packs and occasional airing
If you must use plastic bins
- Add large silica gel packs (or moisture absorbers)
- Do not store the bin on a cold concrete floor
- Open and air it out occasionally during long storage
Avoid
- Garbage bags as long-term storage
- Damp basements
- Unconditioned sea containers (unless you control moisture inside)
How To Clean Inflatables Step 9: Store in the right place (this matters more than people think)
Even if you pack perfectly, a bad storage environment will undo everything.
Best storage conditions
- Cool, dry, consistent temperature
- Off the floor (use pallets or shelving)
- Away from direct sunlight (UV breaks down materials over time)
- Away from chemicals and fumes (paints, gasoline, solvents)
Basements and garages
They can work if you:
- Run a dehumidifier
- Keep inflatables elevated
- Avoid storing near exterior walls where condensation forms
Warehouse storage
If you manage multiple inflatables for corporate events or trade shows, build a simple process:
- “Return check” table
- Cleaning area
- Drying zone with fans
- Final inspection and labeling station
This kind of workflow is exactly what keeps high-visibility branded assets campaign-ready all season.
How To Clean Inflatables Step 10: Label everything (future-you will thank you)
If you run events, you already know how it goes. You pack fast, you move to the next city, and six weeks later someone asks, “Where’s the dome skin?” or “Which bag is the arch?”
What to label
- Inflatable name (client + asset type)
- Event date last used
- “Cleaned + dried” checkbox
- Missing parts list (if any)
- Blower model needed (if applicable)
- Repair notes (tiny tear, scuff, etc.)
Even a simple tag system prevents rushed deployments, damage, and mold risk from repacking a not-quite-dry inflatable.
How To Clean Inflatables and Common mistakes that cause mold (and how to avoid them)
How To Clean Inflatables Mistake 1: Packing right after takedown
Fix: Always plan time for drying. If you must pack immediately, unpack and dry again within 24 hours.
How To Clean Inflatables Mistake 2: Cleaning with too much water
Fix: Wipe-clean. Avoid soaking seams.
How To Clean Inflatables Mistake 3: Storing on concrete
Concrete “sweats.” Moisture rises and condenses. Fix: Store on pallets or shelving.
How To Clean Inflatables Mistake 4: Keeping it sealed for months
Fix: Add desiccants, choose breathable storage when possible, and air out periodically.
How To Clean Inflatables Mistake 5: Ignoring a mild smell
That smell is your early warning system. Fix: Re-clean and do an extended dry cycle before long-term storage.
A practical cleaning + storage schedule (for event teams)
If you’re managing inflatables for activations, roadshows, festivals, trade shows, and corporate events, here’s a realistic cadence.
How To Clean Inflatables After every event (minimum)
- Dry wipe or spot clean
- Dry thoroughly
- Pack with airflow in mind
- Label with date and notes
How To Clean Inflatables Every 3 to 5 events (or monthly during busy season)
- Full wipe-down wash
- Deep dry cycle with fans and dehumidifier
- Inspect seams, anchor points, and high-stress zones
How To Clean Inflatables for the End of season
- Full clean
- Full dry (extra time)
- Condition check and minor repairs
- Pack for long storage with desiccants
- Store elevated, cool, and dry
Special notes for different inflatable types
TMP Inflatables produces a wide range of custom builds, and each category has a few storage quirks.
How To Clean Inflatables like Inflatable arches

- Big surface area means big opportunities for trapped moisture
- Pay extra attention to seams and panel overlaps
- Dry in sections with fans moving around the structure
How To Clean Inflatables like Advertising balloons and hanging inflatables
- Check tether points and connection seams
- Avoid storing with ropes wet or tangled against printed surfaces
How To Clean Inflatables like Mascots and inflatable costumes
- High-contact areas pick up sweat, oils, and dirt
- Dry inside surfaces thoroughly
- Never store while even slightly damp, these can mildew fast
Air dancers
- Bases and lower fabric sections get dirty
- Let the tube fully dry before compressing
- Avoid long-term storage with the fabric crumpled tight
Quick FAQ (real questions we hear all the time)
Can I use a pressure washer on my inflatable?
Not recommended. It can force water into seams and damage print and coatings. Wipe-cleaning is safer for long-term durability.
How long should I dry it before storage?
Until seams and folds are fully dry. In humid environments, that can take several hours with fans. If you’re unsure, wait longer.
What if it rained during the event?
Do not store it long-term right away. Pack for transport if you must, then unpack and dry within 24 hours.
Should I store it inflated?
Usually no, unless you have a clean, climate-controlled space and it’s part of a permanent installation. For most event teams, clean, dry, and properly packed is the practical approach.
What’s the best way to prevent smells?
Clean off organic grime, rinse well, and do a serious dry cycle. Most smells are moisture plus residue.

FAQs (Frequently Asked Questions)
Why do inflatables get moldy even when they seem dry?
Inflatables can develop mold because mold needs moisture, warmth, and organic material like dirt or skin oils to grow. Moisture can get trapped in seams, stitching lines, Velcro strips, zippers, folds, or bases that sat on wet grass. Even if the surface feels dry, slightly damp areas inside folds or seams can lead to mold growth during storage.
What is the most important rule to prevent mold on inflatables?
The key rule to prevent mold is to clean, rinse, dry thoroughly, and then dry again. Drying time matters more than washing time. Fully drying all parts of the inflatable—especially seams and folds—and storing it where moisture cannot get trapped is essential to avoid mold, weird smells, sticky surfaces, and stains.
What basic supplies do I need to clean and store inflatables properly?
You need simple cleaning supplies such as mild dish soap, soft microfiber cloths, a soft-bristle brush for textured areas, two buckets (one for wash water and one for rinse water), a spray bottle (optional), and clean towels. For drying and storage, use a floor fan or air mover, a dehumidifier if possible, a clean tarp or drop cloth for staging, breathable storage bags or covers, desiccant packs like silica gel for bins or bags, and labels for organization.
Which cleaning products or tools should I avoid when maintaining inflatables?
Avoid using bleach as it can weaken coatings and discolor prints. Harsh solvents such as acetone or alcohol-heavy cleaners should not be used because they damage materials. Abrasive pads can scratch and scuff printed surfaces. Pressure washers are also discouraged since they can force water into seams and cause moisture trapping.
How should I prepare an inflatable before wet cleaning?
Before wet cleaning, perform a dry-clean step by sweeping or shaking off loose dirt and debris. Use a dry microfiber cloth to remove dust and lightly brush textured areas to loosen grime. This prevents dust from turning into muddy streaks or being pushed deeper into seams during wet cleaning.
What is the recommended method for spot cleaning stains on inflatables?
For spot cleaning high-contact zones like entry points, bases, handles, or areas near fans/blowers: use a mixture of warm water with a few drops of mild dish soap. Dampen (not soak) a cloth with this solution and gently wipe the stained area. Follow with wiping using a clean water-dampened cloth. For sticky residues like soda or sunscreen, start with warm soapy water; if stubborn stains remain, try diluted white vinegar (1 part vinegar to 5 parts water) applied on a hidden test spot first to ensure no print fading occurs.
