Our sprinkler system has sprayed well water on the side of our brick house and it is all rusty looking. Wondering if anything can be used to remove the rust.

    Hi Julie, you can use oxalic acid. Just follow the directions and let the chemicals penetrate the brick before scrubbing off with a stiff scrub brush and then rinse with water from a garden hose.

      knowledge is power........Cheap vinegar is almost always processed synthetically using petrochemicals. This means that although you think you are cleaning with an environmentally friendly product, you are in fact contributing to the environmental degradation of the planet by purchasing a product made with petrochemicals. So what's so terrible about petrochemicals? Plenty:Exposure to petrochemicals may take place in different ways; they may be absorbed through the skin or might be ingested. They can also affect human life by accumulating in tissues/organs and cause brain, nerve and liver damage, birth defects, cancer, asthma and hormonal disorders.

      Pretty much everything about petrochemicals is damaging to the planet. For a brief introduction to the harmful effects of petrochemicals, check out this ehow page. If you are interested in more in-depth information, many scholarly articles are available for purchase online.

      Thankfully, you don't need to give up on vinegar entirely if you want to clean green because companies still produce vinegar made from grains. It is more expensive than the alternative, but when you weigh the cost of environmental degradation, the extra cost becomes worth it.

    This is an easy one! Buy lots of CLR. Put it in a spray bottle and concentrate on a small patch at a time. Don't get the bricks wet with water before you spray with CLR. Give it a few minutes to work and then hose it down. If you find it's being a little stubborn, use a stiff bristled brush on it and then rinse. Put a baffle behind that sprinkler or replace with a head that doesn't spray on the bricks. It's a lot easier to prevent it than it is to repair it.

    Put a rabbits foot in your back pocket if this doesn't help.
