above ground plumbing turning white

[jeffreymlewis]

Today I began replacing stickers on my above ground plumbing. I decided to scrape off the old stickers (and adhesive residue) with a putty knife. After repeated scraping, the pipes started turning white (see attached picture). That is, I seem to have begun scraping off the black coating from my pipes.

Is this a sign of trouble? If so, what can I do (short of replacing the pipe)?

Is it safe to use ammonia-based cleaners (aka Windex) on these pipes?

Thanks,
Jeffrey

Welcome

All the PVC plumbing started off white (there are some black ... but rare). After install, the builders painted it to try to protect it from the sun's UV rays.

You did not hurt anything ... just buy a can of spray paint
