Microfiber on Tinted Windows

Are microfiber towels safe for wind tint film? What about clear plastic surfaces? I know these are probably dumb questions, but I've never used microfiber towels and want to make sure they don't scratch.

Thanks.

I don''t know about clear plastic...but I''ve never had a problem with scratching my tint.  the paint on my car scratches more easily than my tint does.
