Vacplus Toilet Bowl Cleaners - 30 PACK, Automatical-Cleaning Toilet Bowl Cleaner Tablets for Deodorizing & Descaling, Long-Lasting Bleach Tablets for Toilet Tank Against Tough Stains

One small tablet in tank of the toilet lasts several months! When I flush, it smells like bleach, but it cleaned both my old toilet from iron stains and it kills the bacteria that smells.

It does work really well I had blue stains on my back toilet, which are gone now it has a bleach smell, which is a clean smell nut. Nothing wrong with that. I’d buy it again.

These keep the bowl cleaner than ever. I'm not sure how long they last but I will be ordering more when the last one goes into the tank. Only downside is there sometimes a strong bleach smell.

Great price and your fingers don’t go blue!

I like these. I scrubbed my toilet and now I put one of these in the tank and it's really maintaining the clean!There is a very small scent of bleach but its very faint. That's how I want a clean bathroom to smell.Very good price.
