Automatic Toilet Bowl Cleaner, Repel Rust And Hard Water Stains With Every Flush, Household Toilet Cleaner, Pack Of 1, 6 Tablets, White

Was so useful. Did the trick for what I would have paid lots of money for someone else to do.

These last and work really well. But considering how a toilet works, some of the toilet water will go into the bowl when it’s flushed without going through the upper tank and getting treated by the tablet. This may make a person think it’s not working. Oh but it is! So what I did was I adjusted the top tank to use a little more water per flush. It’s going to need it to flush with how I retrofit the water. I took the hose that puts water directly into the lower bowl upon flushing, skipping the tank area and aimed it into the top tank instead of the lower fill tube. I used the hose clip on the fill tube to make sure it sprayed water into the opposite side of the tank, from where the tablet is so it wouldn’t prematurely break down the tablet. Now it refills the tank faster. The lower bowl part only gets “treated” water. No more yellow rusty toilet bowl! It’s unscented. Not messy. I don’t touch the tablets directly be use it’s a chemical of course.

So glad not to see the orange stripes in my toilet bowl any more...Iron Out is awesome

Didn't work for me

Gets rid of black hard water stain in the bowl. May take a couple if yours is BAD..
