Homebrew PCBs

I bought a brand called, "Clear-All Positive Drain Cleaner" at ACE Hardware in Los Angeles. There are lots of different brands. Just make sure that it has >90% sulfuric Acid. Do a search. For example,

The acidic products are 100 times better at cleaning a drain than those based upon sodium hydroxide, but be sure to follow the directions for use. There was a lawsuit filed by an idiot who used one of these products. He dumped a bottle down his drain and then for good measure he poured in a glass of water and of course, it exploded all over him.
