Notes
Remove the drain screen or stopper and clear visible gunk first. Other mixes : 1/2 cup each baking soda and vinegar (plug 1 hour, then boiling water); 1/2 cup each baking soda and lemon juice; 1/2 cup each salt and baking soda (30 minutes to overnight).Safety: don't pour boiling water into PVC pipes, a porcelain sink or a toilet — use very hot tap water instead. Never use after a commercial drain cleaner is in the pipe. Label the jar.
