What is laundry borax?
It is a comparatively environmentally friendly cleaner that can be used as a laundry additive or used in general cleaning. See this site for more info: http://www.20muleteamlaundry.com/index.c… It is poisonous if ingested by people or pets, though. I have used it in my mailbox (after explaining to my mail carrier what it was so they didn’t worry) to keep spiders out of there.
