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)

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

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

After using twice we still have the same issue

We have tried everything to get rid of a bad smell and stain off a urinal and using this helped so much after leaving it overnight!

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...

Liked the results.

I used this on 3 urinals that were draining slow and had already been snaked. I let it sit for 48 hours and it made a significant improvement. The drains now keep up with the water supply. Highly recommended.

was a waste of money as didnt work
