Pressure washers are powerful tools that can effectively clean a wide range of surfaces and objects. However, there are certain things that should not be cleaned with a pressure washer due to the risk of damage or injury. Here are some items and surfaces to avoid using a pressure washer on:
- Delicate surfaces: Pressure washers can be too harsh for delicate materials such as wood furniture, antiques, or fragile decorations. High-pressure water can strip off paint, erode the surface, or cause irreversible damage.
- Windows and glass: The forceful water spray can crack or shatter glass windows, and it may also damage window seals and frames.
- Electronics: Water and electricity do not mix well, so using a pressure washer on electronics, including outdoor speakers, lighting fixtures, or electrical outlets, can cause electrical hazards and destroy the devices.
- Vehicles: While pressure washers are commonly used for car washing, using high pressure too close to the vehicle’s surface can chip paint, dent metal, or damage delicate parts like side mirrors or antennas.
- Outdoor outlets and wiring: Using a pressure washer near electrical outlets, power lines, or electrical panels can lead to electrical shocks and pose significant safety risks.
- Roofing materials: High-pressure water can lift or damage shingles, tiles, or roofing materials, leading to leaks and costly repairs.
- Air conditioning units: Pressure washers can damage the fins and coils of AC units, reducing their efficiency and potentially causing malfunctions.
- Living creatures: Never use a pressure washer on pets, wildlife, or plants, as it can cause severe injuries and even death.
- Painted surfaces: High-pressure water can strip paint off surfaces, such as walls or fences, that were not designed to withstand such force.
- People: Never aim a pressure washer at anyone, including yourself. The water pressure can cause severe injuries, including lacerations and eye damage.
Always read and follow the manufacturer’s instructions, and use appropriate nozzles and pressure settings for different surfaces to avoid damage or accidents. When in doubt, consult a professional cleaner for advice on the best cleaning method for specific items or surfaces.
