Under Your Sink Products

I’ve bought several products from Under Your Sink since I’ve decided to do as much of our cleaning greener. I’m impressed by the packaging (brown paper bags), I’m close by so I can pick up, and I’d never go back to non-green cleaners, not even eco cleaners. I’ve used them for cleaning the bathroom, including shower screen and loo, in the laundry for normal washing and oxygen bleaching, and I’m about to make dishwasher tablets. We have a worm-farm black water system so using worm friendly products is important.
