How to Clean a Bounce House or Water Slide (Mold, Mildew & Stains)
What is the 15-minute cleaning routine?
Sweep or shop-vac the loose debris first — grass, sand and glitter grind into vinyl if you scrub over them. Then wash the surface with warm water and a few drops of mild dish soap using a soft brush or microfiber cloth, working top to bottom so the dirty water runs off.
Rinse with a hose on low pressure and towel off the excess. Skip abrasive pads and harsh solvents: they scratch and dry out vinyl, and scratched vinyl is where the next mold colony moves in.
How do you get mold and mildew off an inflatable?
Mix white vinegar and water 1:1 in a spray bottle, saturate the spots, let it sit 10 minutes, then scrub gently with a soft brush. For stubborn black mildew stains, a paste of baking soda and water on the spot before the vinegar pass usually lifts it. Rinse well and sun-dry.
Avoid straight bleach on colored vinyl — it fades the material and weakens stitching over time. If mold covers a large area or keeps coming back inside seams, the unit was stored wet and needs professional attention (or replacement) — mold inside the seams never fully leaves.
Why is drying the step that actually matters?
Every moldy bounce house we have ever seen was rolled up damp. Vinyl traps moisture in folds and seams, and Florida heat turns a damp rolled unit into a greenhouse. After cleaning, run the blower for 15–20 minutes with the unit inflated, towel the seams, and only pack it once every surface is bone dry.
This is also why we tell Apopka and Orlando parents renting overnight not to worry about morning dew — our crew handles drying at pickup, and every unit is cleaned and sanitized again before its next party.
- Dish soap + warm water + soft brush = 90% of the job in about 15 minutes
- Mold: 1:1 white vinegar spray, 10-minute dwell, gentle scrub, sun-dry — skip straight bleach on colored vinyl
- Never roll up a damp unit: drying is the single step that prevents mold in Florida
Rather Skip the Scrubbing?
Every Too The Moon unit arrives cleaned, sanitized and dry — that is the whole point of renting.

Can I use a pressure washer on a bounce house?
Low pressure only and never up close — high PSI forces water into seams and stitching. A garden hose with a spray nozzle is safer and just as effective after a soap scrub.
Is mold on a bounce house dangerous?
Surface mildew cleaned promptly is not a health crisis, but established mold can trigger allergies and asthma in kids. If a rental unit arrives smelling musty, refuse it — ours never will.
How do rental companies sanitize bounce houses?
We clean debris, wash with a vinyl-safe cleaner, disinfect contact surfaces and dry fully between every rental — read our cleaning practices.
