How many cars do you do a week? What do you do to each car?
Regular hose & bucket wash, (A rarity for me anymore)- 1 or 2 for drying
Rinseless wash- 2 for drying
Waterless wash- 2 to 6
QD- 2
Spray wax- 2
Remove polish- 1 or 2
Remove wax/sealant- 1 or 2
Windows- 1 or 2 waffle weave
Door jambs, wheels, tires, wheel wells, underhood, trunk, I use old cotton terry towels. My MF towels only get used on paint or glass.
40 or 50, maybe more. Only about 10 of them are waffle weave and I only use them for windows.
Years. I probably have some that are 6 or 7 years old. I don't think I have ever "worn out" a MF towel.
