The 100% cotton bonnet is ideal for removing dried polishes and waxes, and gentle polishing. The hooked fibers are excellent at removing residue and gently polishing the paint surface. The cotton bonnets can also be used to gently scrub interior surfaces with your Cyclo polisher. Cyclo Cotton Terry Bonnets should be placed over clean, dry foam pads for cushioning. Put one microfiber bonnet over each foam pad on your Cyclo polisher.
