You should rent a pressure washer if you only use it once or twice per year or simply don’t have the space to store one. Renting is a great way to get a quality pressure washer for only a couple of hundred dollars per year. However, if you’re using a pressure washer regularly, it’s usually a better idea to buy one. Even with storage and any repairs or maintenance you might have, you’ll still end up saving money in the long run.
Pressure washing must be avoided on surfaces that are prone to damage. Delicate surfaces such as shingled roofs, glass, electrical components, and items with sensitive seals cannot withstand high-pressure water. Using a pressure washer on these materials can strip protective coatings or cause permanent damage, leading to costly repairs and compromised safety.
Pressure washer performance is measured by pounds per square inch (PSI), which specifies the force at which water is delivered. A pressure washer with a higher PSI means greater cleaning power for grease and stubborn stains, while a pressure washer with a lower PSI protects delicate surfaces from damage. Most pressure washers deliver between 1,000 and 5,000 PSI, depending on the type.
Pressure washing your deck is effective for quickly eliminating dirt, grime, and mildew, and this technique is suitable when the deck is in sound condition. The ability to clean without altering the surface structure makes it ideal for maintenance; however, if your deck requires surface preparation for refinishing, sanding may be preferred. High-pressure water can remove the superficial buildup while preserving the natural texture of the wood.
