Using Chemicals as Effective Drain Cleaners
For severe clogs, slowly apply 500 ml (half of a Liter bottle) of sulfuric acid to the clog. Let sit for an hour, and then test for drain opening by applying water. If the clog has not been cleaned out, apply another 250ml or 500 ml of sulfuric acid and allow to sit for another hour. Continue adding sulfuric acid if clog persists.
