Advice
The oil is caused by improper stacking / storage of the BOSU® Balance Trainers. All plastics and Vinyl in this case are made from oil. When you stack the trainers where the blue ball portion is touching a black base of another unit, it will pull oil out of the ball. This is normal and goes away once washed with a mild cleaner and stacked base to base or dome to dome.
Store your BOSU® Balance Trainer out of direct sunlight. Store platform side down, dome side up. For multiple Balance Trainers avoided dome to platform contact, they should be stacked either dome to dome or platform to platform.
Two reasons this issue may occur: 1) over-inflation, or 2) exposure to sunlight and/or heat sources. The dome should only be inflated between 8.5” to 10” high. The owner’s manual covers this information on pg. 5, “Care & Storage” and pg. 7, “Getting Started.” To fix the BOSU® Balance Trainer, remove the plug (use a spoon to help with this,) deflate the dome completely and remove bolts from each side of the clamp, click here for instructions. Then, work the bladder-ribbed edge to fit back onto the base, fit the clamp back on, tighten and re-inflate the unit. This should solve the issue. For repair instructions, please contact Customer Service.
You can try using a Vinyl patch from an air mattress, pool liner, or waterbed that can be picked up at your local hardware store. We also recommend trying a product found online called AirStop . It comes in a tube like toothpaste. Several customers have had success with this product. AirStop is made for patching Vinyl footballs, basketballs, soccer balls, etc.
Your BOSU® Balance Trainer may need time to settle once inflated. There can be a “hissing” air noise that is a normal occurrence from the dome settling on the base platform. As long as your unit is retaining air there is no need to worry.
