Four things you should avoid cleaning with a pressure washer

Laminate Flooring
If you have laminate flooring in outdoor spaces, using a pressure washer is definitely unsafe. The intense pressure can lift the laminate, damage its protective layer and push water beneath the layers – resulting in warping or buckling.

Windows and Glass
While it might feel like a simple method to eliminate dirt, smudges and fingerprints – windows and glass are not suited for pressure washing. The high-pressure water can crack or shatter the glass, which could lead to expensive repairs or replacements. Even tougher glass types, such as double-glazed windows, are at risk because water can infiltrate the seals, causing long-term problems like fogging between panes.

Aged Concrete
You might assume that pressure washing is appropriate for concrete due to its durability. However, older concrete surfaces can actually suffer damage and cracking from pressure washing. High-pressure water can erode the top layer of concrete, particularly if it has already been weakened by years of environmental exposure. This erosion can result in pitting, cracks or spalling (flaking off).

Electrical Panels and Meter Boxes
It’s obvious that combining water and electricity is a dangerous mix, which is why electrical panels, meters, outdoor outlets and any other electrical devices should never be subjected to pressure washing. The high-pressure water can penetrate electrical components, potentially causing short circuits, electrical fires or even total equipment failure.
