Clorox® Washing Machine Cleaner with a septic tank

Advice from Dr. Laundry
Q.

Can using Clorox® Washing Machine Cleaner affect my septic system?

A.

I have good news for you: Clorox® Washing Machine Cleaner can be safely used to clean clothes washers that drain into septic systems–septic tank operation is not affected by regular home use of the product. Additionally, when used as directed, Clorox® Regular Bleach2 is safe for use in septic systems. The bleach breaks down rapidly to mostly salt and water.  Please let me know if you have any other questions, and thanks again for writing!
