Instructions

1. Remove as much standing water as possible from sink or tub. Make sure water in drain is cool. 2. Slowly pour 1 heaping tablespoon of Crystal Heat Drain Opener directly into drain. Do not allow product to contact any sink or tub surface or fixture. Damage may occur. 3. Add 1 cup of cold water to drain. Immediately cover drain opening with a bowl to avoid splash back. Do not completely seal, as pressure can build up. 4. Once drain has cleared, flush with cold water. 5. If drain remains clogged, repeat steps 1"5. Avoid physical contact with standing water in sink from the first application, as burns may occur. 6. If after two treatments the drain remains clogged, consult a plumber. Wear gloves and goggles when handling.

Pro-Tip: Crystal Heat boils away the toughest build up. If the first application does not work, reapply. 32 doses per can.

Horrible product
Size : Case of 12
The crystals turned into a concrete like substance. The pipes had to be replaced. We could not even get a snake (with a drill like head on it) to bust through the concrete like substance caused by this product. I would give this product negative stars, if I could.

Best for tough Clogged drains
I have a Plumbing business in which We use this product on supper backed up drains. We pour a half a cup down with cold water. Once the water gets to it you will hear sizzling and a vapor will come out of drain. I suggest you use a mask and gloves. Let it work for about 15 minutes. After the vapor and sizzling stops try running the faucet. If it doesn't work out the first time do the same thing again. We usually do a treatment then snake the drain. The product will loosen the clog for the snake to get through. The other drain this is good for is your condinsation drain for your ac. I have been in the plumbing business for 35 years and Highly recommend this product.

the best drain cleaner I know of
crystal heat works awesome, but definitely wear gloves and don't let water get near it until it's in the drainand if your sink is already full of water, you'll need to wet vac it out before using crystal heat or else this will happen to youthis was a major chemical bomb when it happened, I was forced from the room by the caustic cloud that was erupting from the sink in a storm of bubbles - it set off the smoke detectors in the house, had to evac me and the dog to a shed in the back yard during a blizzardI'll still use Crystal heat, it really is the best thing I've found, just be really careful with italso, keep the once opened container in a 1 gallon baggie just to be safe
