Therapy Clean is a family-owned small business based in Dover, New Hampshire.

My former colleague Brittany Ross says, “I don’t know what kind of fairy dust this plant-based spray is hiding inside, but it made my mucked-up fridge sparkle within a MINUTE! I was skeptical when I first sprayed it onto my fridge because it took a second for the streaks to start fading, but lo and behold, there was *zero* residue left behind after a super brief wipe sesh. Once I saw how downright dazzling my fridge looked, I decided to put it to the ~real~ test — my filthy dishwasher. Again, a minute of buffing with a microfiber towel was enough to make it look like a brand new appliance, and it worked wonders on the greasy stainless steel edges of my oven, too.“

Promising review: “I live in an apartment. The sink is about 35 years old and has become badly stained and scratched from neglect and indifferent care. This has made a noticeable difference. This sink will never look brand new again, but your product removed, I would say, about 80% of the stains, without any extraordinary effort, and put a really polished look on the sink. It is gleaming and actually looks very clean for the first time since I have lived here. —David Brennan
