Expert Answer

If you need to treat a large area, or if you don't want your bathroom to have a pungent vinegar scent, you can dilute the vinegar with water in a 2:1 ratio. This will give you more solution to spray and cut the smell without lowering the anti-fungal power of vinegar!

Question

If I don't have an essential oil, will this still work?

Community Answer

Yes. The oil is just for a pleasant smell for the cleaner, it is not required, or part of the cleaning power.

Question

I have a fiberglass bathtub, and this weird pinkish orange stuff keeps staining the bottom. What is this, and how do I get rid of it?

Community Answer

This happened to me, and I found it was a result of the Dial Gold soap we were using. We like the Dial Gold, however, and will not stop using it, so we just clean with diluted bleach spray every so often.

Question

How can I get rid of the lines of lime in the water line of a toilet? I have tried over the counter products that claim to take care of the problem and they don't work.

Community Answer

Undiluted vinegar overnight will start to break limescale down, don't forget to brush vigorously as well! Some cleaner brands seem better at removing limescale. In the UK I find that Harpic works well whereas all the Duck brands are good at cleaning but leave limescale largely intact.

Question

For method one, am I mixing the bleach/water solution with the peroxide/baking soda?

Community Answer

For method one, use the baking soda solution first. Then, once you've finished removing as much mold as you can with that mixture, use the bleach solution. You are not mixing them together. (Also, there is no peroxide in method one.)

Should I take cold showers to reduce mold in the tub?

Not necessarily, mold grows because there is moisture or water particles floating around. If there is water there is mold.

Will mold keep coming back in a shower due to poor ventilation in a bathroom?

Poor ventilation, moisture, and darkness make for an ideal breeding grounds for mold, so, yes. If you have a vent in the rest room, leave it on during and up to an hour after a shower.

Question

Do I need to wear a mask? Can I breathe in the spores?

Community Answer

It is highly advised to use a mask or face-covering as protection when removing bathroom mold. Though most mold species will only cause allergies or asthma-like coughing, it is recommended to use protection during the process.

Question

Will wiping with paper towels and adding bleach to a moldy tub get rid of toxicity?

Kaitlyn Wislang

Community Answer

Bleach kills mold on non-porous surfaces such as bathtubs. You can also try a white vinegar or Borax solution. A cleaning cloth or scrubbing brush might also be more effective than using paper towels.

Question

Mold grew behind the wall of the shower due to a water leak. I have sprayed the studs with anti-mold spray that I got at Home Depot. Will the studs need to be replaced?

Community Answer

No. If the bleach does not kill it, sanding down with sandpaper and then sealing it with a wood sealer will stop the re-contamination of mold.

You can remove the mold using a cleaning solution made with either white vinegar, Borax, or bleach. If the mold is spread over an area larger than 10 sq ft (0.93 m2), contact a professional cleaning service instead.

Question

Are baking soda and borax the same thing?

Borax is chemically different from baking soda, but the two products share many uses. Both are useful for household cleaning in the kitchen and bathroom and to freshen laundry. Both are also eco-friendly and green alternatives to commercial cleaning products.
