Run your bath, add this jet cleaner, have allllllll the grime come out of said jets, and then wipe down your tub. BOOM! You’re done.

Promising review: “OK, so I love to clean and I run bleach through the jets prob twice a month on top of my daily weekly cleaning. And I was skeptical how this product could get it any cleaner than I thought it was. Well, I am here to tell you this pic is after the second cleaning with this cleaner!!!! I am a believer and would highly recommend this product to anyone with jetted tub!!” —Momof2greatboys
