What's the best choice to remove mold from a brick bedding wall?

[Baitball Blogger]

I found this option: Is there anything better out there?

Wet and Forget claims to be environmentally safe and no water pressure spraying needed:

1. Just did this - Borax, vinegar and bleach. Make a thick mix, paint on and spray off.

2. I have too many trees and shrubs in the area to try this.

But, I will keep it in mind for difficult areas.

Thank you.

6. Just mix some water in with the bleach at maybe 70 water/30 bleach.

Borax can be used to kill some plants ans grass, but when used in small amounts it can be beneficial to soil. Vinegar is the same. Both borax and vinegar are acidic. When mixed with water, both are rather harmless. Concerned about the plants? Just cover them with plastic while you are working and then rinse the wall well with water. The rinse water will also dilute the cleaning solution.

3. How about bleach mixed with some water in a spray bottle?

4. I am trying to avoid anything toxic that might seep into the ground where the tree roots will

get to them.

5. I think Clorox is pretty benign.

Not anymore toxic than that brew from Home Depot.

7. We use bleach in a spray bottle on our white siding to get rid of any spots

after pressure washing it. Put it on, leave it and the spots disappear. Doesn't seem to bother anything under where we spray.

8. ''Is Wet and Forget safe for plants?'' Not completely, according to their FAQ

Is Wet and Forget safe for plants?

Is it safe for plants and flowers? A: When applying Wet & Forget to the surface, the runoff into surrounding soil will not harm plants. However, when you are spraying Wet & Forget we recommend to protect your nearby plants/grass from overspray by rinsing them down before and after you apply the Wet & Forget with water.

11. How about organic Neem Oil which is used to kill fungal diseases in gardens ...

or maybe plain hydrogen peroxide (?)

Black Mold Removal With Hydrogen Peroxide
Eliminating black mold with hydrogen peroxide is another great alternative to chlorinated bleach. And, is not harmful to the environment to boot.

It is non-toxic, does not leave a toxic residue after use, is very inexpensive and produces no toxic fumes. It also serves wonderfully as an antiviral, antifungal and anti-bacterial agent. https://www.howtoremoveblackmold.com/how-to-kill-black-mold/#tab-con-6

12. ''Getting rid of black mold with tea tree oil ...''

Getting rid of black mold with tea tree oil has many advantages over using corrosives such as bleach or ammonia based mold cleaning products.

Going green with tea tree oil is not as cheap as using bleach or ammonia. However, a small amount of tea tree oil will go very far in effectively getting rid of black mold. And, the environment and your lungs will thank you for it!

Tea tree oil is a natural fungicide that is effective at killing black mold spores and getting rid of mildew throughout the home. It will work for you equally as a cleaner and as a mold prevention agent.

13. If I can spray it on and wash it off with a hose, that might be the thing.

14. that has copper in it, may kill plants. it looks like overpriced pool algeacide (which shouldn't go

in pools, either. the copper is where the green hair thing comes from, not chlorine)

dilute bleach is what you want. it won't hurt anything for long even at full strength, (grass and weeds will grow back after a dose of full strength) dilute then rinsed with more water dilutes it even more, then sun deactivates it and turns it into a little bit of salt. the chlorine gasses off when combined with any dirt or other organic matter. household bleach is anything from bargain price crap that is 6% or less to so-called extra strength at 8% putting a 1/4 cup in a gallon of water will not hurt anything (except maybe dark fabric). Start there and work up to higher concentrations. give it time to work - several minutes at least. the bleaching/cleaning may continue for longer unless rinsed.

15. I used baking soda and it worked a treat

Baking soda does work, I found this method online, tried it and it worked a treat.

This is pretty much exactly what I did..

Step 1 - First of all you need to get some baking soda and you'll need some water as well.
Step 2 - Start to mix the baking soda and water (equal parts) until it forms into a paste.
Step 3 - Using a rag, cloth or sponge you need to apply the paste to the mold and leave it until it has dried.
Step 4 - Once it has dried you'll need an old brush to scrub off the dried paste from the mold.
Step 5 - Then simply wipe away any remaining baking soda.


To try and stop the mould from growing again you can try mixing two tablespoons of baking soda and two cups of water into a spray bottle and spraying the effected area. There's also some really good info here: https://www.mouldcleaningaustralia.com.au/black-mould/

16. Thank you, and welcome to DU.

Anything would be better than the "spray it and forget" I used. It worked on the concrete pavers, but killed my grass bigly.
