Your household cleaners may be toxic, so take care before your toss any of them out with the trash or pour them down the drain. Don't dump drain cleaners; use them completely according to the manufacturer’s directions. Aerosols should be entirely emptied before throwing out. Bleach can be diluted and poured down the drain, but never mix it with ammonia or other acidic cleaners. Other cleaners and polishes should be used completely or allowed to dry in their container before discarding.
