Iron OUT Rust Stain Remover Powder, Remove Rust Stains In Bathrooms, Kitchens, Appliances, Laundry, And Outdoors, 4.75 Pound Bottle

Worked brilliantly wit minimal effort. Probably terrible for environment

Really, really worked. Most of the rust came off first time from the toilet and just went over it again to take off the last traces.

Excellent product...will buy again

Good product worked well
