🙋 FAQ: RV Water System Sanitizing
Can I use vinegar instead of bleach?
While vinegar may help with odors, it’s not as effective at killing bacteria. Stick to bleach or commercial RV sanitizers for full disinfection.
How do I get rid of the bleach smell?
Flush thoroughly with fresh water. You can also add a tablespoon of baking soda to help neutralize any remaining odor.
