Javelin Urinal Drain Treatment – Industrial-Strength Urine Salt & Scale Remover – Unclogs & Restores Urinal Drains – Eliminates Odors & Prevents Future Build-Up – 32 Fl. Oz. (1 Bottle)

This stuff does it job.

Used to use this exact product many times for many years at work in urinals. Worked great on my toilet buildup at home. Will be flushing #1 every time from now on. Only needed half the bottle. Seems a bit expensive but it does work.

Helped me a lot of times. Didn’t need to use plumbers service

works great. gets rid of smell

Worked wicked pisser!

This is the only product that clears the backup

Considering the price, and that you have to use several bottles to make any difference in uric salts, this drops considerable rating, because you just can't solve much issues with just one bottle.

Work urinal smelled like caca, caked with pee salt that look like white rock/crystal and barely flows. I dumped half a bottle in the urinal, waited 2 hours, and, like magic, 99% of the rocks are gone, looks and flows like brand new, one no longer need to hold their breath when doing #1. Now it does stink BAD while it is soaking/working it's magic. Imagine the smell of an open sewage tank along with heavy sulfur, but that's what exhaust fan is for. Not sure if the smell is harmful but I would not stay inside and would suggest you to NOT use this product unless there are some form of exhaust fan within the space because you WILL need it running full blast.
