Pressure washing is a powerful cleaning method that uses water at high pressure. However, applying too many pounds per square inch can damage certain materials and items. Recognizing what you should not pressure wash helps prevent costly damage and ensures safety.

Things You Shouldn’t Pressure Wash at High Pressure

Wood Siding

Using high pressure to wash wood siding can cause significant damage. The force of the water can strip away protective coatings, exposing the wood to the elements. This leaves the wood vulnerable to rot and decay. Additionally, high-pressure water can force moisture into the wood, causing it to swell and warp. This water damage compromises the structural integrity and aesthetic appeal of the siding. It’s best to use lower pressure or soft washing techniques to clean wood siding without causing harm.

Asphalt Shingles

Pressure washing asphalt shingles is not advisable due to the risk of dislodging granules that protect the roof. These granules shield the shingles from the sun’s UV rays and rain. When dislodged, the shingles become more susceptible to weather damage and can deteriorate faster. This leads to potential leaks and costly repairs. Gentle cleaning methods should be employed to preserve the integrity of asphalt shingles and extend the roof’s lifespan.

Old Mortar

Old masonry, especially with crumbling mortar, is at risk when exposed to high-pressure washing. The intense water pressure can push out the weak mortar, leading to gaps and structural instability. This can result in costly repairs or even more severe structural damage. Use gentle cleaning techniques to avoid dislodging mortar and preserve the structural integrity of older brick or stonework.

Electric Panels and Meters

Power washers should never be used on electric panels and meters. The high-pressure water can penetrate the seals and insulation, causing short circuits and potential shock hazards. Water ingress can also lead to equipment failure and costly replacements. Always clean electrical components with appropriate, non-invasive methods to ensure safety and functionality.

Vehicles

Using a pressure washer on vehicles can be detrimental. High-pressure streams can strip away paint, leading to rust and corrosion. The force of the water can also damage seals around windows and doors, causing leaks and compromising the vehicle’s interior. To avoid these issues and maintain the vehicle’s finish, it’s best to use a gentle car wash designed for automotive surfaces.

Painted Surfaces

Pressure washing painted surfaces can result in premature paint removal. The high pressure can strip the paint, causing the need for unnecessary repainting chores. This not only affects the appearance but also exposes the underlying material to the elements, potentially leading to further damage. Using low-pressure washing methods is advisable to clean painted surfaces without harming the paintwork.

Air Conditioners

Pressure washing air conditioners poses significant risks. The high-pressure water can bend or clog the internal cooling fins, reducing the unit’s efficiency. Additionally, water ingress can damage the electrical components inside the unit, leading to costly repairs or replacements. It’s best to clean air conditioners with gentle methods to avoid damaging the delicate components.

Windows

High-pressure washing windows can be dangerous. The force of the water can break seals, damage frames, and even shatter the glass. This not only leads to expensive repairs but also compromises the insulation and security of the windows. Cleaning windows should be done with low pressure or by hand to ensure they remain intact and functional.

Aged or Fragile Concrete

Using a pressure washer on aged or fragile concrete can cause significant damage. High-pressure water can etch the surface, creating pockmarks and weakening the concrete. This reduces the structural integrity and aesthetic appeal of the concrete. It’s better to use a lower-pressure or specialized surface cleaner to clean older concrete surfaces without causing harm.

Living Plants and Animals

It should go without saying that pressure washers should NOT be used on animals. The force of the water can harm plants in your garden or lawn, stripping leaves and damaging stems. Keep a safe distance from plants and animals when using a pressure washer to avoid unintentional harm.
