The Dangers That You Should Know
Before you combine bleach and vinegar to kill mold, you should know that bleach is a powerful chemical that is dangerous if not used properly.
Most chemicals are highly concentrated and give off a strong aroma as a warning sign to not inhale or ingest it. Bleach is one of those chemicals. Thats because one of the main components found in bleach is chlorine, which is poisonous. While small amounts of this chemical are relatively harmless, large amounts in bleach can be incredibly toxic if used incorrectly.
Breathing in or ingesting these chemicals can be fatal, so proper safety precautions should be taken at all times so that these risks are minimized.
Vinegar is more natural and poses a lesser risk, but the combination of the two is equally as dangerous as bleach is alone.
What Kind Of Vinegar Should You Use
First, save the apple cider vinegar for salad dressing. To clean mold, use regular white distilled vinegar, typically sold with five percent acidity. You can also use cleaning vinegar with its six percent acidity. Both are effective at killing mold. Generic brands are as effective as name brands.

Preventing Mold Problems In The Bathroom
- Inspect your toilet for leaks. Look for wet areas on and around the toilet, as well as on the water line that connects the toilet to the wall. If you notice any leaks, call a plumber as soon as possible. Leaks can hike up your water bill, damage your home, and foster mold growth.
- Test for leaks with food coloring. Add six or seven drops of food coloring to your tank and let it sit for 30 minutes. Then check your toilet bowl and see if the water has changed color. If it has, you’ve got a leak. Call a plumber right away!
- Don’t use your toilet as a garbage can. Avoid flushing paper towels, feminine products, cleaning wipes, or anything other than toilet paper.
- Check the water shut-off valve. This is the knob attached to the wall or floor that shuts off the water supply to your toilet. Just turn the knob to make sure it is still turnable. If it is resistant or won’t budge, it may be faulty and in need of professional maintenance.
- Make sure the fill valve is working properly. Lift the lid to your tank and flush the toilet. Make sure that the after the tank has refilled, the fill valve completely stops dispensing water. If it doesn’t, give us a call! Our highly-skilled plumbers will promptly diagnose and fix the problem.
If you spot mold, or see signs of water damage due to your septic tank backup, schedule a mold inspection and remediation with a MICRO-certified mold remediation specialist or water damage specialist to assess any and all damage.
