Review on 🚽 Down John: One-Year Supply Septic Tank Treatment | Eco-Friendly Concentrated Bacteria & Enzyme Flush | Eliminates Odor, Cleans Lines & Improves Field Absorption by Danae Velasco

Revainrating 3 out of 5

Aside from carbon stains, it works well on my sewage treatment plant

I've been using Down John for four years now and it seems to work well on my sewage treatment plant. My only issue is that the first day treatment, which is a carbon additive, messes up the toilet bowl. It is very difficult and messy to remove. On the advice of Dawn John, they said that to remove the stain, I had to mix up a solution of baking soda and water to manually clean the bowl. My toilets are ToTo brand and obviously made of material that has carbon attached to it. It's such a dirty clean that I'm looking for another product.
