i just got my motor back from the shop, he told me to clean the motor out real good a few times before we actually build it, so im wondering what people are using to clean a freshly honed wall and not ruin it?

i was using scotchbrite pad (green one from publix) but i see some faint vertical scratches that i think it left, so im wondering what i should use to clean this!?

 

paper towels and wd-40. clean it really well until no metal debris appear on the towel. works perfect

 

Gasoline, soap & water, Marvel mystery oil. You cannot get it too clean.

 

wd-40 and bounty(lint free) paper towel for cylinder sleeves.carb/brake cleaner for everything else
