How to Use Bleach As a Drain Cleaner

Pure, undiluted bleach containing sodium chloride--what is commonly referred to as "chlorine bleach" or "regular bleach"--can be used to clean household drains and prevent clogs. Non-chlorine and color-safe bleaches are not as effective in this usage. However, this type of bleach requires you to follow usage guidelines because it is a dangerous chemical.

Things You'll Need

• Chlorine Bleach

Instructions

1. Pour 12 ounces of the correct type of bleach into the sink or tub whose drains you wish to clean.

2. Leave the bleach sit for 30 minutes to an hour for slow drains or routine cleaning. For stopped drains and severe clogs, allow to sit overnight.

3. Flush the bleach with hot water. Make sure to wash all traces of bleach from the basin and drain because some materials, such as stainless steel, will corrode or discolor if exposed to bleach for long periods.

Tips & Warnings

• Though chlorine bleach was once thought harmful to older plumbing, most plumbers now believe bleach will not degrade pipes regardless of their composition or age.

• Do not mix bleach with other cleaning substances. Bleach and ammonia create chlorine gas, which is harmful and often fatal. Many store-bought cleaners contain chemicals that will react with bleach.
