You Should Never Power Wash These Things
Power washing might look like a good task to indulge in at your house, but beware of all the limitations of a highly pressured water hose, as ignoring the safety tips and harm both you and the surface you’re working on.
Firstly, you should hire a reputable power washing company like https://www.mapquest.com/us/maryland/bethesda-barons-power-washing-423969075 to on the safe end, as they know their limitations and the surfaces they can’t work on. But if you’re keen to do it yourself, here are some surfaces you should avoid while power washing.
Wood Siding
Usually, the pressure washing companies are able to wash the wood siding carefully, but you shouldn’t do it by yourself. If you use a high amount of pressure on the wood siding, the water will surely make it’s way in the inner surface of the wood, and will start damaging it. If water gets under your wood siding, it can damage lots of other things like electrical wiring, insulation and might also cause the molds to grow inside.
Asphalt Shingles
Washing an asphalt shingle fitted roof with power washer can become a nightmare for you. Asphalt shingles have some granules inside them which are important to keep your roof safe from elements, but high pressure of water can cause those granules to leave the singles. Additionally, you shouldn’t use the pressure washer when standing on a ladder, as the recoil can push you backwards, and you might suffer from a serious injury.
AC Unit
Using a pressure washer on your AC unit is a big no. The fins of your air conditioner can suffer from damage due to the high pressure of water coming out of the high pressure water hose, this can restrict the air flow from the air conditioner.
To clean an AC unit properly, you should use low pressure water and a vacuum for the best results.
