So, if I do use OA, I should soak rags in it, wrap them around the infected area for 12 hours, rinse with water, then use a nylon brush or Scotchbrite pad?

But since I do not have OA (I may go out and get some), I could use white vinegar-soaked towels, wrap the infected area for 12 hours, then remove with nylon brush or Scotchbrite pad?

Thanks all!

BTW, the bike is just the last bike listed in my signature.
