r/Mold↗
Mold Facts, Regulations, Info and How To Cleanup and Remove
/r/Mold is an educational and informative subreddit for redditors trying to deal with mold in their homes, apartments, work places, etc. It IS NOT a place to have your mold identified. You need laboratory analysis for that. This is also not the place to post photos of moldy food. We can't tell you if it's moldy or if it's safe to eat. And DON'T POST PHOTOS OF DIY PLATES/TEST KITS
