How to clean aluminum siding
When cleaning aluminum siding, there are several approaches you can take. Many people choose to use a pressure washer for washing aluminum siding since it makes the job immensely easier and generally cuts down the time required to clear out bigger staining and larger messes.
Power washing aluminum siding is suitable for most projects but if you notice any loose or damaged pieces, mildew, or other issues, it may be best to use a brush to get a deeper clean without risking damaging your home by pushing water into already degraded areas. If there are any damaged spots, repairs should happen before pressure washing or you should opt for a more gentle and less invasive method.
How to remove aluminum siding stains
If you are attempting to remove more intense, set-in stains, you can use a hands-on treatment to target the dingy areas. Mix your cleaning solution in a bucket and use a soft brush or cloth to apply a liberal amount to the stained area and scrub gently until the spot has faded. Then, follow up with a pressure washing treatment and repeat as needed.
When looking at how to clean painted aluminum siding, you have to use a more gentle method to prevent the paint from chipping if there are damaged areas in the paint. If there are areas where the paint is peeling, it is a good idea to remedy that issue before power washing or scrubbing to prevent further damage unless you are planning on repainting anyways.
How to remove mold from aluminum siding
Treating mold on aluminum siding can be trickier than just removing the spot with a cleaner. To kill off the source of the mold, mix up a solution of one part bleach to four parts water and scrub the area liberally. This should kill it at its source and aid in preventing the spot from reforming.
Alternatively, mildew on siding is much more difficult, as it tends to reoccur more frequently and easily. Mildew lurks in cracks and areas that do not see much light, making it hard to notice until it has already spread. The treatment for mildew is similar but may have to be repeated more often since it regrows more easily.
How to pressure wash siding
As mentioned in the how to clean house siding segment, pressure washing siding is a very effective and time-saving way to approach cleaning your home. To power wash your home, mix the cleaner to the labeling’s specifications and use it as it says to. Then, simply use the power washer to scrub away the residue and staining with ease instead of opting for a hands-on brush method.
This method of restoring aluminum siding can prove especially effective for older stains and spots, as the high pressure of the cleaner works to blast off and sort of resurface the spot, exfoliating and eroding away any residual staining surface area. It is also great for cleaning aluminum siding oxidation for the same reason.
Power washing requires precautions. You should wear appropriate safety gear, as dictated by your instruction manual and you should always ensure there is no chance of you accidentally spraying someone, as high-pressure water cleaners can break the skin and cause serious injury if they come in contact with a human or animal. They should also not be pointed at windows or cars unless the product in use is specifically designed for these types of applications, which most are not.
