Cleaning Up this Brick - Pressure Washing ?
 
102 Attachment(s)
What's a good way / chem - solution to clean up this brick ?

I only know / use Simple Green and bleach on siding and works great.

I get in there and brush everything but with what ?

I saw some Krud Cutter brand for masonry this evening. $12 gal - which usually doesn't go to far.

Just hit it with a pressure washer - kill the rest w/ bleach solution if you must.

Got some spalling going there - gonna take care of that too?

I would use D/2 to remove the mold, its a biological cleaner and protects for up to a year. Its expensive at $40 per gal but works well. The carbon staining can be removed with a good restoration cleaner, Hydroclean HT-626 is a great product

Brick can be a pain.
 
I have found a bio barrier helps at least keeping the funk from coming back for some time. I have found obliviously bleach kills the green mildew but removing that dirt build up can be tough. Hot water helps. but just hitting it and taking your time with this work is the best solution. I have been tempted on a couple of brick jobs to bust out the sledge hammer though. I have a lot of 100 to 150 year old brick homes and buildings in my area and I know for a fact bleach doesn't do too much with it. A good acid based cleaner. any good pressure wash supplier in your area will have some great detergents for brick. I order most of mine out of Atlanta area they seem to be the best in my area. Let us know how it comes out.

Krud Kutter
 
Oh and please stay away from krud kutter. It is junk no matter what strength you use. Add some spic and span and save some money. It actually works better than krud kutter. I was in a jam and went this rout after spending 30 bucks on that junk. I now use Power House wash. It has changed my results tremendously.

yes, definitely first try a commercial grade pressure washer, and afterwards use a bleach solution... if still needed, can always get some industrial strength mold remover product.

apply some bleach and a surfactant, let dwell for 10 minutes, then hit with pressure washer.
We pressure wash a lot of brick patios here in Baton Rouge

We renovated a school quite a few years back and it had architectural panels over and under all the windows. It also had about 30000ft sq of brick to clean. We started off with 2000 psi washers and ended up using 5000 psi. The panels were slimy green when we started and beautiful white like new when we were done. The brick turned out great as well but you had to be very careful. Any mortar joints that were weak were soon found with the pressure washer.
