Used it to clear out my 8sleep. I believe it works

I wasn't really sure what to expect for this. I saw on a reddit forum about purchasing this to mix with water in the 8sleep to clear out any of the bacteria or nastyness that ends up clogging the drain lines and breaking the machine. I used 3x the strength on the bottle and filled/flushed 3 tanks worth. It went from not working at all, to working like it did from when I first purchased it. I wish I would have been using this stuff from the start and would have avoided having to break down the machine entirely and working tirelessly with 8sleep's dreadful customer service.
