Pressure Washing FAQs, answered by experts

You should never use bleach in a pressure washer. While bleach is effective at killing mold and mildew, it is a potent chemical that can corrode the machine's seals and nozzles, destroying it from the inside out. Additionally, pressure washing with bleach sprays the chemical into the air, which is dangerous if inhaled and can kill nearby plants, flowers, or harm animals that ingest it. If you need to remove mold or mildew, it is best to hire a professional who will use a safe and effective cleaning agent.

Jet washers can last for up to 10 years, but a more exact timeline for your jet washer depends on the frequency of use and maintenance. Some machines are given a rating of their approximate total hours of usage, which can help determine how long yours will stick around based on how many hours you use it each year. Aside from learning how to properly use the jet washer, you’ll want to keep it stored safely and securely so that it won’t rust or get damaged between uses.

Whether or not you can use a pressure washer to clean your gutter guards depends on the type of gutter guard you have and the strength of the pressure washer. Most gutter guards can handle a low-pressure setting but check first. If you’re unsure if your gutter guard is designed for pressure washing, check your manufacturer’s instructions, ask a pro, or use a garden hose to clean the gutter guard instead. As gutter guards age, they become less resistant to the strong forces of a power washer, so treat older gutter guards with more care.

No, pressure washing isn’t recommended for cartridge filters. The high pressure can damage the filter paper, and the gentler pressure from a regular garden hose will work to rinse the cartridge filter. If the cartridge is very dirty or has algae or mineral buildup, you can use a muriatic acid solution to soak the filter and remove the buildup.

The answer to how often you should pressure wash your house is the same no matter whether your siding is wood, metal, or vinyl. Plan to do a project like this once a year with occasional hand cleanings in between to remove unexpected dirt—like debris from an especially violent storm or droppings from birds flying overhead.
