Take a few minutes and learn something!
To address some questions/comments I’ve gotten:
Liquid Plumr Foaming Pipe Snake will still clear a clogged drain, but (based on some Google searches of the product’s reviews) you may have to use two bottles.
You use the entire bottle of Foaming Pipe Snake to clear your drain.
The sodium hydroxide doesn’t react with bleach or peroxide. It its incorporated into the saltwater/oxygen foam.
