I use a lot of towels during a detail....maybe 20-25 towels a car...I use one for every panel during polishing to wipe it down...one for each door jam...one for inside windows and one for outside windows...one for each wheel...3 in the engine area....3-5 on
LSP removal...and so on....I try to keep a minimum product build up on a towel...and getting them to grimy also...much easier to clean that way
