How to Clean a BOSU Balance Trainer
A BOSU Balance Trainer has a flexible dome joined to a rigid platform with a recessed valve and plug. Cleaner residue on the dome can make it dangerously slick, while harsh solvent, soaking or pressure cleaning can affect the material and seams. BOSU's official care resources use mild cleaning and emphasize inspecting and storing the trainer correctly. This guide removes sweat and floor grime without unnecessarily disturbing the plug, flooding the base or treating a loss of inflation as a cleaning problem.

Step-by-step instructions
Step 1: Identify the model and inspect inflation
Confirm whether you have a full-size Balance Trainer, Pro model or another BOSU product, because construction and inflation directions can differ. Before adding moisture, look for a bulge, cut, separated platform, loose hardware or a plug that is not seated. Do not exercise on a structurally questionable trainer simply because its surface can be wiped clean.
Step 2: Place it on a clean stable floor
Move the trainer to a floor free of grit and sharp objects. Do not balance it on furniture or hold it by the dome while scrubbing. Brush or vacuum the surrounding floor first so the clean surface is not immediately contaminated when the unit is turned over.
Step 3: Remove dry grit from the dome
Use a dry soft cloth or nonabrasive brush to lift hair, sand, chalk and dust from the dome texture. Work gently around molded markings and the platform edge. Dry removal prevents grit from scratching or being smeared into the flexible material by the wet step.
Step 4: Wash the dome with mild solution
Dampen a cloth with warm water and a small amount of mild compatible cleaner. Wipe the dome in overlapping sections, paying attention to hand and shoe contact zones. Do not use solvent, bleach, concentrated disinfectant, abrasive powder or an oily conditioner. Never pour cleaner onto the dome or submerge the trainer.
Step 5: Remove all slippery residue
Use a separate cloth dampened with clean water to lift soap from the dome. Repeat until the material feels clean rather than slick. A fragrance or shine is not proof of cleanliness; grip security matters. Dry with a towel and do not step on the dome while any moisture or cleaner remains.
Step 6: Clean the rigid platform and base
Turn the trainer using both hands and support the platform. Brush debris from textured recesses, then wipe with the mild solution and a rinse cloth. Keep liquid out of the valve and plug area, screw recesses and the junction between platform and dome. Do not pressure-wash or steam the underside.
Step 7: Inspect the valve and plug without removing them
Wipe around the accessible valve recess with an almost-dry cloth. Do not remove the plug merely to clean around it; repeated or improper removal can create an air-loss problem. If inflation needs adjustment, use BOSU's exact pump and inflation instructions rather than guessing from dome firmness alone.
Step 8: Air-dry both sides fully
Place the trainer where air can reach the dome and platform without prolonged intense sunlight or a heater. Rotate once the first side dries. Do not stack or store it while seams or textured recesses remain damp, because trapped moisture can support odor and make the next setup slippery.
Step 9: Test stability and store correctly
Set the dry BOSU on its approved exercise surface and press it by hand to confirm stable inflation and platform contact. Stop for hissing, progressive softness or a separated edge. For multiple units, follow BOSU's stacking guidance—matching base-to-base and dome-to-dome orientations—rather than crushing a dome under a hard platform edge.
