When it comes to pressure washing, it’s important to understand that not all surfaces are suitable for this type of cleaning. While power washing is a great way to remove dirt, mold, and other contamination from hard surfaces, certain materials can become damaged if they are subjected to too much pressure or heat.
Some of the items you should avoid when pressure washing include:
-Fine masonry features– Certain masonry details like grout lines may be lost under intense water pressure so it’s best avoided for these sensitive areas around stone structures like fireplaces or granite countertops in particular.
-Shingle roofs – Similarly with wood siding and decks, shingle roofs should not be exposed to high water pressures since their integrity will eventually deteriorate under sustained impactful pressures causing leaks in some areas eventually down the line leading up costly repairs that might have been avoided originally..
Overall while pressure washer is useful tool for hard surface cleaning but extra caution must be taken when using this technique as there are risks involved depending on what material is being cleaned because even powerful machines have limits; hence why its always recommend seek professional help whenever dealing with jobs bigger than your capabilities handle!
