"And leaving micro scratches in the paint work"

So, whats your suggestion then ? Leave it dirty, don't wash it, in case
it gets micro scratches ?

I would imagine that the original poster has more on his/ her mind than
the unavoidable "micro scratches" which being micro in the first place,
not many people are going to notice.

AND I prepare my cars for sale using this method

AND I've never had too many sitting around because of micro scratches.
Grow up or don't bother posting sh*te.
