Unblock Toilet Caustic Soda __hot__ -

Caustic soda can unblock a toilet, but the risks often outweigh the convenience. Use it only when mechanical methods fail, and treat it with the same caution as a laboratory chemical. When in doubt, call a professional.

Do not leave it overnight, as the dissolved debris can settle and re-harden, making the clog worse. : unblock toilet caustic soda
