Bricks, Masonry, Asphalt and Concrete - Cleaning paint "chalk" from exterior of home

I am hoping for some suggestions on how to remove old paint chalk lines from the exterior of our house. We have tried paint stripper and it lightened it some, but mostly just smudged it around a bit. We were told muriatic acid but we tried that also and it did nothing. Some help would be wonderful.

I assume you mean that you are trying to remove the places where the chalking from the paint has stained the brickwork on your house. Soap and water might help some. The problem is that brick is quite porous and will hold the fine particles from the chalking of the paint.

It would help to wash the exterior painted surfaces of your house annually with some soap and water and hose it off well. The paint is supposed to chalk to keep itself clean. If the paint is old, 10 -15 years, and seems to chalk overmuch, it may be time to freshen the paint. Newer paint won't chalk as much simply because it is newer.

Hope this helps.

I have a two story house with aluminum siding that is in perfect condition but the surface color is too beginning to fade.
I mention this because I almost made a serious mistake.
I bought a cleaner that is supposed to be sprayed on to wash the surface and brighten it up.
One thing I didn't notice when I first read the instructions was that this product contained silicone!
Had I used it, I would have ruined my chances of repainting because silicone is almost impossible to remove and would have prevented me from painting the siding which I will be doing probably next year.

It really, really pays to read the instructions and such that come with products we want to use. Many times, folks create problems that did not exist because of using something without reading the directions or following a friend's advice.
