Deadly Drain Cleaner

Just putting this out there. Bought LiquiDrain to clean a drain. When I poured it into the drain it exploded all over me. Burnt through the gloves and my clothes. Very bad burns on my hand and arm. Requested Builders and the manufacturers to warn people about the volatility of this stuff and have not had any joy from either. So please be warned... Do Not use it! Worst of all didn't fix my drain problem.
