Dos and Don’ts of Pressure Washing
Pressure washing is a quick way to wash away gunk from a variety of surfaces. It is easy to get carried away, but pressure washing every surface around your house is not the best idea. Doing so can potentially damage paint and nick or etch wood and some types of stone. Wondering which surfaces should and shouldn’t be pressure washed? Keep reading:
When made from South American hardwoods like Camaru, Ipe, and Tigerwood, these decks will hold up to pressure washers. Decks made of pressure-treated wood, such as southern yellow pine, can typically hold up to the pressure as well, as long as the nozzle is not held too close. Start with a low-pressure nozzle to make sure the spray does not harm the wood. Work along the length of the board and go with the grain of the wood.
Using a pressure washer to clean your roof is dangerous and can cause damage. Never use a pressure washer while standing on a ladder as the pressure of the blowback could cause you to lose your balance. It can loosen the shingles on your roof and even strip asphalt shingles of the embedded granules that help extend its life. If mold and moss is the issue, spray the roof with a cleaner that kills mold and mass or spray a 50/50 mixture of bleach and water.
Concrete can handle pressure washing without much etching. A finer nozzle is usually more effective in spot-cleaning grease stains. If your cement is moldy or covered in mildew, coat the surface in suds and use lower pressure.
Whether or not you should pressure wash your siding depends on the type. Vinyl siding and fiber cement siding can typically hold up to the pressure. Aluminum siding can dent, so start on the lowest pressure setting with a broad nozzle. Wood clapboard siding can be pressure washed, but have your exterior paint tested if your house was built before 1978. If lead paint is knocked loose, it will never break down in your soil as it is a heavy metal. When using a pressure washer to clean siding, make sure not to let water get trapped between the siding and your home’s sheathing. Do not pressure wash shingle siding as the pressure can knock the shingles loose.
