Don't really matter what size you use I like it big enough to fold over a few times, plus a heavier thicker towel so I can put real good down pressure on the towel because yes it's for when your done grinding spray the tire good and that is the final clean and it actually appears to polish it off as well , So I just pointed out if you use a longer towel be aware of where the xtra length hangs so it doesn't wrap up in any part of the machine turning .Thanks for the answers and suggestions.
Some suggestions on how to do it. I have a belt sander, just got me a new variable speed 7" angle grinder and have different grades of sand paper. Have been using windex as a coolant.
I see racing promoter says use a big towel. I assume that's a final wipe. I really need to get all I can out of the tires I have. Don't have a huge selection. Have a good set of white vegas and a good set of pinks and blues. Krug has been used on them so I will stick with that. Just need to figure out the best way to use it.
I usually wash my tires off at the track. Just get the dirt off of them.Not my video but a very similiar process that I use.
