2 Tablets, Whink Toilet Bowl Cleaners, 4 Ounce

Just put one in the toilet tank about every 6 or 8 weeks. My maid loves it, It has removed just about all rust from the tank over a period of about 6 months.

this product is excellent, they have changed it some, but still works better than anything else i've found. I'ts very hard to find anyone who sells it. Trader Horn is where I always got it , till they closed this spring.

I took away 1 star because the cleaners melt so quickly and have to be replaced often. It was amazing when I dropped one into the toilet tank the rust immediately started dissolving off the sides of the tank. I had cleaned the bowl with CLR and a lot of muscle to get the rust ring off before adding the Whink. These has helped tremendously keeping the bowl clean in our hard water.

We live in the country and have well water with some iron. These tablets are very effective in preventing iron stains in the toilet bowls in our house. I have tried numerous brands of toilet bowl cleaners, but none have ever matched the top-notch performance of Whink's RustGuard. The only problem is that this product is not always easy to find in our local stores.

I'm delighted at how easy Rustguard works. Clean the bowl and drop a tablet in. It stays spotless until the tablet is completely gone. (No icky residue is left, unlike other brands). I've tried every major product on the market, with no luck. The mineral in our well water is just too tough. Mom has the same problem, and gave me a package of Rustguard. (I should have gone to her in the beginning. Mom's always know how to fix this kind of problem!) Rustguard can be hard to find, but if you have a high mineral content in your water, this is what you need. If you can't find it at your local Wal-mart, Amazon usually has it in stock.

Best I have ever used to keep toilet ring free

RustGuard works exactly as it's promoted to work.

I moved into a house with rusty toilets. This cleaned them in 24 hours!

This is the only thing that keeps rust out of our toilets. We have tried other products, and they don't keep the rust out.

Use their liquid cleaner bottled product that Whink sells on a weekly basis and it's absolutely beyond this world amazing so I thought that being made from the same company and the same product, only difference is one is in liquid form one is in tablet form, basically the same ingredients. I thought I would have the same result unfortunately it did absolutely nothing. Sadly no different than the dollar bleach tablets you drop in the toilet that smell good for one day and clean for zero days!! Very disappointed!!
