Eco-Friendly Drain Opener
No, no, no, set down the caustic drain opener and walk away.
Instead, if you have a clogged drain, pour 1/2 cup of baking soda and 1/2 cup of vinegar down the drain and then let it sit for 15 minutes. Next, flush with boiling (or for PVC pipes, hot tap water, see update below) water.

Update: We just read that you shouldn’t pour boiling water down the drain if you have PVC pipes. Hot tap water is suggested instead.
