Get matched with top pressure washers in Millis, MA

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.

Combining power and soft washing is a great way to ensure that all surfaces, both fragile and not, get the attention they deserve. Start by power or pressure washing durable materials like vinyl siding and concrete pavement or driveways, then switch the tips on your machine and finish up by soft washing the more delicate elements, like shutters and front doors, for example. 

Yes, pressure washing a wood deck can be a good idea as it effectively lifts ingrained dirt, mold, and mildew, improving the deck's appearance and longevity. However, it must be done carefully, as it's easy to damage the wood, especially softwoods. To pressure wash safely, use a lower pressure setting and a wide, 40-degree fan pattern nozzle (often white). Keep the nozzle at least a foot away from the wood surface and maintain constant motion, avoiding hovering in one spot to prevent gouging.

The white nozzle is your best choice for power washing indoors. The white nozzle, or the 40-degree nozzle, comes with a pressure even lower than the standard green nozzle but still has enough force to clean the surface. It works great for painted and wooden surfaces. It also doesn’t damage more delicate materials like ceramic or tiles. However, avoid pressure washing delicate furniture, caulking, and other surfaces that require more tendered touches than regular surfaces.
