CREW 04560 Heavy Duty Toilet Bowl Cleaner & Disinfectant, 23% HCI removes Rust Stains, Lime Scale with Mint Scent, Ready-to-Use, 32-Ounce

Excellent product, very good for cleaning bathrooms. I recommend it.

FINALLY A PRODUCT THAT WORKS. We had a slab leak and had to use our toilet to do dishes. It made a terrible ring in the toilet. I've been trying for 2 years. FINALLY SOMETHING THAT WORKS. No harsh scrubbing. Just add it to the toilet and come back in 20 minutes. CLEAN CLEAN CLEAN. Thank you.

I have a 20 year old toilet that used to flush super fast. Over the years mineral deposits and bacteria growth made the parts I can't reach very rough, so many times it wouldn't flush all the way. My family wanted me to buy a new toilet. I picked this product because of the very high HCl content. I didn't follow the directions! I turned off the water and flushed the toilet. Then I poured half the bottle into the toilet and let it sit for 6 hours. WOW the toilet now flushes like new!

Professional strength

This cleans lime and rust very well. Be sure to use appropriate PPE, it’s hard core cleaner. Only con is that it is thin; not clingy. Wish it were more viscous and clingy. Definitely gets the job done.

This product is everything it claims to be. I used it as directed. I mixed it in a used bowl cleaner bottle in order to get under the rim. Those using over two ounces per mixed bottle are using too much. Be patient, it will work. I've used many cleaners through the years on and off the job and this is by far the best. With just one ounce it did the job.

I strongly advise against purchasing this product. Based on my experience, it's been diluted with water and has an unusual thickness, unlike the original. Buyer beware!

We bought a house that was sitting empty for a few years with gross, rusty, lime deposit covered toilet bowls. We tried everything until this was recommended by a friend. It doesn’t smell harsh, and it cleans the remaining stains so well! Worth the price. Easy to use. Great product!!
