Had a severely clogged kitchen sink drain. That clog was far enough down in the drain pipe that it caused water to back up and freeze solid in the sub-zero winter we are having here in Michigan. Nothing was working to clear it. I took apart the drain system under the sink to get to the pipe that lead directly out to the system. Found reviews of Crystal Heat and ran over to Home Depot. I followed directions, poured it directly down the drain pipe, heard a bunch of commotion, and suddenly black gunk began to spew back up the pipe. YUCK! I had my Shop Vac handy to suck up the mess. IT took me 4 tries at this. I kept pouring more crystals in and kept taking up the gunk it was melting away. After an hour, I sucked up this horrible black ball of disgusting tar from the depths of the pipe and that was the end of it! Drain runs quicker than it ever did since I have owned this house. Great product!

Rated 5.0 out of 5.0Â by Autobroker The best way to clear a drain.
I'm going back a few years, but there was a product called Red Devil Lye that was available at the grocery store. It was very inexpensive and did a great job. Well, I heard that Lye (Sodium Hydroxide NaOH), is used to make illegal drugs, so Red Devil Lye is no longer on grocers shelves.
I was glad to find Crystal Heat at Home Depot. I read the label and yes, this is NaOH. My tenant had a clogged drain, so I did my usual routine. First, I open the window. If possible, I run hot water down the drain (if it's slow) and get the pipes nice and hot. I then pour the drain cleaner in - about a couple teaspoons, but I don't measure. I then leave the room and close the door. 10-15 minutes later, I come back in and listen to the drain. If it's still hissing and smoking, I leave for another 10-15 minutes. When there is no more noise, I run hot water down the drain and see if it cleared. If it's still clogged, I repeat. Normally, it takes about 2-3 tries and I usually do one extra to make sure the drains are really clean.
Note that the directions on the container say to run cold water, not hot. If you use my method, NEVER look down the drain and after dumping the cleaner down the drain, get out of the room. You can also leave a plastic margarine tub cover over the drain. This is caustic chemicals, so you need to use extreme caution.

Rated 5.0 out of 5.0Â by Vanessa Cleared a clog nothing else could!
I had a nasty clog in a pipe in my basement that of course drained my laundry tub and kitchen sink out to the rest of the drains in the house. We have been trying everything for almost 2 months and nothing worked, not even a 25' snake. I was just about to give in and call a plumber (sick of doing dishes in the tub and laundry at a family member's house) when we tried Crystal Heat. It smoked and fizzed and took multiple applications to get to the clog so far down the pipe, but it worked! We were shocked to run water this morning to check and not have it back up!

This worked perfectly to disolve hair and grime in my bathroom sink.

Rated 5.0 out of 5.0Â by TMan1 Works great and fast! We've tried Draino and other products with poor results. This stuff opens the drains quick. You can even hear it as soon as you pour it in.
