Clean Cedar Siding With A Household Cleaner

Most commercial household cleaners used for cedar siding have oxygen bleach as its active ingredient, but there are also products with hydrogen peroxide as the active ingredient. These types of cleaners offer no chemical odor or fumes and they are safe to use in areas where they will be exposed to plants, grass and trees. Peroxide wont stain surfaces and it degrades quickly over the course of a few hours.

Cleaners using hydrogen peroxide have been found to brighten the appearance of cedar and do not leave blotchy areas, nor do they bleach out the wood or cause the fibers to become brittle like harsher chemicals might.

Most homeowners using products with hydrogen peroxide will apply it with a garden hose attachment and lightly scrub the cedar, or theyll use a pressure washer set on low for a no-scrub approach.

Wash Vinyl Siding Regularly

Going years between cleanings is a sure way to make it a longer cleaning process than it would otherwise be. With regular cleaning, you can avoid having to work long and hard to get rid of stubborn stains or a massive buildup of mold and mildew.

Most homeowners can get by with cleaning their vinyl siding once a year. But if you have particularly wet and humid summers, you could see a buildup of mold and mildew much faster, which means you need to address the problem the moment you notice it.

Furthermore, if you live in an area where pollution and/or dust is a problem, youll likely have to address your cleaning needs on a more frequent basis.

Using A Pressure Washer On Vinyl

Not all vinyl siding manufacturers recommend pressure washing their products, so it’s best to check first to avoid voiding the warranty. Once you’re sure it’s OK, adjust the pressure to no more than 1,200 psi and fit the wand with a 40-degree nozzle. At that pressure, you may have trouble removing well-established patches, especially from high places that require you to work from a ladder. For this reason, it’s a good idea to scrub with a disinfecting cleaner and rinse with the pressure washer. Remember to keep the wand horizontal or tilted downward to avoid forcing water under the vinyl slats.

Repainting Siding After Removing Mildew

If your siding needs to be repainted, choose a mildew-resistant paint.

The most mildew susceptible paints are latex paints, especially when linseed oil base primer is used. Acrylic gloss and semi-gloss latex paints are less susceptible to mildew than flat latex.

The least susceptible paints are exterior enamels. Special paints are also available that contain a mildewcide.

Your local hardware store or paint supplier will be able to assist you in choosing the correct paint and primer to reduce mildew on your home and its effects.
