Would a power washer be the best way to clean my vinyl siding, or would it be better to use some type of cleaner and rinse it off with a garden hose?
It will depend on what you are trying to remove from the siding. Typical house cleaners can be applied, allowed to sit and then rinsed off. More stubborn stains may require a little scrubbing before rinsing. If the siding is severely stained, a pressure washing may be necessary. It’s important that you become familiar with the pressure washer before using it. Practice different pressure nozzles in an area that isn’t always seen. Start with lower pressure and continue to increase as needed. High-pressure water can leave marks, or even cut through vinyl siding if left in one place for too long, so keep the nozzle moving. Be extremely careful when using a pressure washer from higher elevations or off of a ladder. The high pressure can knock you backwards. Use the proper safety procedures to prevent this from happening.
