"Saponification is an exothermic chemical reaction—which means that it gives off heat—that occurs when fats or oils (fatty acids) come into contact with lye, a base. In this reaction, the triglyceride units of fats react with sodium hydroxide or potassium hydroxide and are converted to soap and glycerol."

If you have very hard water, it also can effect how easily the resulting soap can dissolve. I use Liquid Fire available at our local Ace Hardware, as we have very hard water. It is concentrated Sulfuric Acid, probably between 92-95%. It works great for me, but it is friggin dangerous - you need to know these caveats.

1) You must wear protection! If you get concentrated sulfuric acid on you and rinse it off slowly, it produces heat and will burn you unless you flood it. People have lost their eves due to this. Chemical labs using it are required to have a special shower to flood it to prevent this - or maybe mitigate this, if you get concentrated Sulfuric Acid on you, it is most definitely Double-plus Ungood. It is a Goggles and Face Shield kind of dangerous. Chemical handling gloves are handy, too. Wear something heavy and long sleeved, and preferably an apron too. I still have my rubberized chemical handling apron from my chemistry lab days.

2) You need either a high flow exhaust for the room you use it in, or a proper repirator with the correct chemical cartridge. I use the bathroom fan, which if pathetic from a chemical safety standpoint, and a sulfuric acid vapor cartridge, and a face shield, and very thick glasses. I keep the cartidges in ziploc bags between use. If you have an older home, you may discover you bathroom vent exhausts into your attic. This is not good with Sulfuric Acid fumes.

3) If your kid drinks it, they are probably dead - I really don't know what the proper response is to that. Maybe someone can say, I remember a kid who drank acid and they had to replace his esophagus, so I guess it can be survived. If you have younger children, research the emergency protocols for that. I wouldn't keep it in my house until the kids were older. Even now, it stays locked up in case someone else's little kid might be visiting. I prefer locked up in a metal cabinet in the garage, myself.

4) It can melt or crack your pipes. There will be directions on the bottle. FOLLOW THEM. Concentrated acid being diluted in water is highly exothermic. That means it can boil water inside the drain of the toilet, cracking it and spilling a solution of acid that may still be stronger than battery acid (33% sulfuric acid). Or it will melt the PVC drain pipe, which means you have acid all over whatever space is below your toilet. If it's down through your slab, Sulfuric Acid will also damage concrete too. Again, if you cannot follow directions, don't use it. If you are one of those people who cannot resist adding a little more, neither using concentrated Sulfuric Acid nor reloading your own rifle or pistol rounds is advisable. Think Darwin Awards.

Also, with any acid, never ever mix with bleach. The resulting Chlorine Gas has killed people.

By the way, Hydrofluoric Acid is sometimes available as a drain cleaner - I once had access to an industrial supply company that dealt in part with the plumbing trade. I haven't tried to get it in a couple of decades, preferring Sulfuric Acid personally. Sulfuric Acid typically reacts better with many organic substances you can find clogging your drains.

was reading some of the reviews on Amazon that it solidifies in the pipe and makes the clog even worse, is this true?? They even upload some pictures of white solids in the pipe after they cut the pipe open.

It is better to buy it off the store. My 2 cents.
My order from a couple of weeks ago leaked in the box and this item is not eligible for return.

This indeed occurs. Had a tenant use a draino and it solidified the particulates and oils or whatever in the pipes. Had to call Roto-Rooters and boy, let me just say, it was PITA. The snake they used didn't help, had to jet that stuff out...

Get yourself a 25' snake from HD for about $25; works better than this, will last just about forever, and doesn't harm your pipes in the process.
