Get matched with top pressure washers in Dewitt, MI

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.

When you deep clean your washing machine, using hot water is the best practice since it’s more effective than cold water at killing various types of bacteria and viruses. Plus, hot water tends to break down soap residue more efficiently.

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.

The recommended PSI (pounds per square inch) for cleaning vinyl siding can vary, so it's best to consult the manufacturer's guidelines. Generally, vinyl siding can handle high pressure, from 2,500 to 3,500 PSI. For comparison, more delicate materials like wood and aluminum siding should not face more than 1,500 PSI. To safely disperse the pressure on vinyl, use a tip with a wider spray span, such as a green (25-degree) or yellow (15-degree) nozzle. For routine cleaning of light dirt, a garden hose with a spray nozzle may be sufficient. Always exercise caution to avoid using excessive pressure that could damage the siding.
