Rust-Oleum RustGuard Rust Stain Remover

If you have rust stains, you’ve found the right product. I have sorry and bottle. I like the spray, wife likes the bulk bottle. The important fact is this product works , I’ve used for years, you won’t be disappointed!

Not as effective as the bleach filled tablets but no bleach smell is great.

So far so good.

It works!!

Followed the instructions and it's not working for us and our hard water. Also, the tablet turns into a goopy jelly like substance that finds it's way into the toilet bowl. Disappointing 😢

We live in an area with hard water and without something the toilets no matter how much you clean them get a buildup. This product has always worked like a dream. Pop on tablet in your tank and you are good to go until now.....same packaging but the tablet is different. It is a different shape, it feels different and it acts differently. Old vs New tablet lasted a month - tablet now lasts maybe 2.5 weeks tablet used to fully dissolve - tablet now has a funky sack like blob left over tablet used to keep water tank and toilet bowl both clean - tablet now only keeps bowl clean Even after tablet was dissolved, I at times would forget to put a new one in and my toilet bowl stayed clean into the next month - now tablet is not fully dissolved, we aren't even at the 2 week mark and bowl is already getting rust stains Rust stains used to come back gradually - rust stains are back before the month is up. So I am thinking they "new and improved" this product and as often happens it doesn't last as long or do the job nearly as well as it used to.

Excellent product. We have very hard water & builds up quickly. It’s a constant battle using pumice & harsh chemicals that didn’t work well. These stain removal tablets are fantastic! No scrubbing or stress, just drop into tank, stains & limescale gone overnight. I highly recommend!!!

I rent an apartment. Everything was redone before I moved in a few years ago, except they kept the old toilet bowl. I tried clorox inside the tank to clean EVERYTHING from the inside out to remove the rust stains continually building up. I ordered Pumice bars, specifically made to remove rust stains inside the bowl, by hand scrubbing with gloves on. Long story short, I read a lot online and this small item, Rust-Oleum Rust Guard was mentioned as a miracle cleaner for rust. I bought it at another store. Tried it, and followed the instructions very carefully. It’s placed inside the tank, and with every flush the rust stains are being removed. I ran out of the product, and found it at Amazon. It’s the only product I’ll EVER use to keep a white looking toilet bowl. Use it, you won't regret it!!!
