Anyone have a home remedy for killing mold on concrete

[Ray S ECenFL]

Go get you some of the swimming pool chemical "Sock-It". Wet down the patio really well and sprinkle the Sock-It over the entire area. Let it set overnight if possible, then rinse with water.

It may take a couple packs of Sock-It if you have a large patio.

I do not have a pool so I am not familair with the pool chemicals, but will look into this also. Thanks for your input.

Wow, there is a ton of information there. I have browsed a lot of it and most of what I read deals with mold inside the home. I am lucky and it is NOT inside my house. Just on the concrete pavers outside in the backyard. I am going to book mark the link you sent me because it is a wealth of information. Thanks. One item I read:

"For instance, bleach is one of the most common household items that is said to eliminate molds like stachybotrys chartarum. But most bleach is diluted enough that it can’t penetrate deep down below the surface where the real problem lies. If however the fungus hasn’t come into contact with a porous surface such as a kitchen or bathroom countertop, then using bleach may actually eliminate the problem."

My wife has used full strength chlorine bleach and has not solved the problem.

Today, I used a commercial concrete cleaner ( left over from major oil leak on driveway from rental car driven by visiting in-law) and a scrubbed it in to the patio. Washed and followed up with an industrial degreaser (purple stuff). I did this to half the patio to see what the results were going to be. Most of the mold came up. There are still some signs of it but about 75% of it is gone. I have locally purchased some Spray and Forget Cleaner at local Ace Hardware. It is suppose to be some kind of miracle product. I sprayed it on the already cleaned area as well as the other half of the untouched patio.

Saw immediate reaction on the untouched side. I will Spray and Forget it till my Wife starts nagging me about how much worse it looks than before I sprayed it. Will have to get the garden house and brush out again. Until that happens I will wait and see if this stuff works as advertised.

In commercial construction we use muratic acid, though I think diluted clorox will work best in your case for mold. Make sure you have good ventalation in whatever you use ": )

 

[ivan salis]

the acid will work but its brutal on the grass and anything else it touches , wicked bad for anything nearby that it comes in contact with (wild life wize)

Hey, Ray.
If the mold is really into the concrete, you'll need to break the surface tension of the water / bleach mix so that it can go into the pores. Do this with a little bit of liquid soap. Mix in some liquid dish soap by stirring it in, not agitating it. You don't really want a lot of suds.

Bleach and elbow grease is most every professional's advice. Also, once you get it out, seal your concrete, or your patio, or where ever it is growing. And, you DO have to find out why you are getting it - a leaking downspout or a leaky window, or a bad drip edge on your roof - whatever it is.

Hospitals use bleach for a reason - bleach is the only thing that NOTHING can live in - including the aids/HIV virus and all other viruses.

Even teaching first aid and CPR, the medical community has gone to cleaning Resuscitator Annie with bleach, for that very fact. Plus, hydrogen peroxide will turn into plain water if left open, or when it gets older, thereby losing any effectiveness it may have had. It's great for bacteria and organic matter, but will not kill most viruses.

Mrs. O:
Back in the 1960s, there was some stuff discovered in Viet Nam that even Clorox couldn't wash off. At least........ that was the rumor.

turn them over no really Im not joking

 

[Ray S ECenFL]

It takes a while for the Spray and Forget Cleaner to do its job but the paito is looking much better. The half that was only sprayed with the Spray and Forget is as clean as the half that I scrubbed on with two different products. Impressive. Will give it a few more weeks to work and then I will seal the stones with a concrete sealer.

Thank you all for your advice.

Shortstack,

That may be true - but we are speaking of natural surface bacteria, mold and viruses.
