I have read where some detailers using ceramic spray wax / sealers elect to only use a microfiber towel once before discarding due to potential ceramic particle build up in the microfiber towel could scratch the finish on subsequent uses when vehicle detailing with ceramic wax / sealers ? I wash and reuse microfiber towels but never thought of this possibility of ceramic particle build up in microfiber towels - your thoughts and experiences on this topic ?
