CRETE Urinal Drain Cleaner, Commercial Grade, Restores Pipes to Original Diameter, Urinal Descaler & Deodorizer, Safe for Pipes, No Harsh Fumes, Urine Salt Remover, 16 Fl Oz (Pack of 1)

This stuff worked great. We have had a problem with calcium build up and our urinal overflowing at our store for years. We had it cleaned by a plumber once before and it cost about $500 dollars. This was a cost effective solution to an on going problem. If you use it take a shop vac and suck the drain hole dry. Then pour in and leave at least overnight. Flush with very hot water several times and you should be good to go.😉

Had a clogged urine, cleared after leaving product in overnight. Must clear as much water as possible before pouring in. Super easy to use and clean up

Didn’t work as described. Didn’t clean as described. Left a weird after smell.

This product is amazing. Poured in and left for 48 hours. Opened a completely stopped up urine crystal related toilet blockage.

Works great

I am very pleased with this product it really performed better than I expected. I recommend this for anyone who has a bad urinal clog.

I am beyond impressed. My urinal was clogged for over a month! I tried all the drain cleaners possible with no success, then I heard of Crete. I put it in my urinal and the liquid initially sat in the urinal. I came back 45 minutes later and it was all in the drain. I flushed 12 hours later and the clog is completely gone!! Thank you

This potent smelly acid cleaned the line surprisingly fast. I guess after 5 years stuff builds up. Who knew? I might be using it once each year or two...
