Get matched with top pressure washers in Lancaster, MO

Brick takes longer to dry than less porous materials like concrete. If you are waiting to spot clean, a full day of mild weather should do the trick. If you are waiting to paint or apply a finish or sealant, give it three to four days to ensure the brick is absolutely dry as a bone. You don’t want any residual moisture whatsoever before laying down paint or sealant. 

The best soap for a pressure washer is a mild multi-purpose cleaning agent. Mild dish soap works, but make sure to dilute it with a 1:4 ratio of soap to water to avoid clogging your machine. Sometimes you won’t even need a detergent when using a pressure washer. It all depends on how grimy your furniture is to start with.

If you don’t use the right PSI setting for your fence’s material, then yes, pressure washing can ruin your fence. Specifically, if you use a PSI that's too powerful, you may permanently damage a fence. Pressure washers can also remove paint from fences, though this can be a great thing if you’re looking to restore an old wood fence.

You should avoid using a pressure washer on any surface or item that could be damaged by the high-pressure spray, as some materials are too delicate to withstand the force.

Key items and surfaces to avoid include:

• Electrical Components: Never pressure wash electrical systems, as water can cause short-circuits and create a safety hazard. This includes utility meters, breaker boxes, electrical outlets, generators, and HVAC or air conditioner units.

• Delicate and Fragile Materials: Fragile items can crack, shatter, or be stripped by the pressure. Avoid pressure washing windows, glass, light fixtures, shingled roofs (especially asphalt), and stucco.

• Painted, Stained, or Sealed Surfaces: Unless your goal is to strip the finish, do not pressure wash painted surfaces, stained wood (like decks), or anything with a protective seal that could be stripped away. Be especially cautious with older surfaces that may contain lead paint.

• Soft Woods and Certain Decking: Delicate surfaces like softwood, composite decking, and antique or wooden patio furniture can be etched or damaged. If you must wash wood, use a lower-powered pressure washer with a wide-angle nozzle to prevent damage.

• Living Things: Never use a pressure washer on people, pets, or plants. The force can cause serious injury and will destroy landscaping.
