Should you pressure wash wood siding?

• <div><p>We don’t recommend pressuring washing clapboard siding. At high levels of pressure, a pressure washer can damage wood siding permanently. Pressure washing can also make it easier to drive water into the cracks of clapboard (which are recommended for easier drainage), causing moisture damage.</p><p>If you think your clapboard siding is so dirty it could benefit from pressure washing, we suggest contacting a pressure wash cleaning service and getting a quote on a wood siding project. Some siding manufacturers recommend never pressure washing because it can force water behind the siding.</p></div>

Q: Do you turn the pressure washer on before the water?

• <div><p>You should always hook up your pressure washer to the water supply before turning it on and ensure there&rsquo;s a good water flow. If you try to turn the machine on without water in the system, it overworks and overheats the unlubricated pump. This can quickly lead to irreversible damage.</p></div>

Q: What is the best soap for pressure washing outdoor furniture?

• <div><p>The best soap for a pressure washer is a mild multi-purpose cleaning agent. Mild dish soap works, but make sure to dilute it with a 1:4 ratio of soap to water to avoid clogging your machine. Sometimes you won&rsquo;t even need a detergent when using a pressure washer. It all depends on how grimy your furniture is to start with. </p></div>

Q: What do you spray on a wood deck before pressure washing?

• <div><p>Before pressure washing, you can spray your deck lightly with a deck cleaning solution made of equal parts oxalic acid and water. Oxalic acid has a brightening effect that will lighten mold stains and return the deck to its original freshly-sawn look. Allow the solution to sit for about 20 minutes before pressure washing so it has time to take effect.</p></div>

Q: Should you pressure wash tennis courts?

• <div><p>Some hard surfaces, such as concrete and asphalt, tolerate pressure washing well, and it can be a great way to keep them clean. However, you should avoid pressure washing clay or grass as you'll quickly destroy them.</p><p>Additionally, pressure washing can remove paint lines from any surface, so you need to be careful, and it may be best to let professionals handle the job.</p></div>

He had the soil brought in by truckloads, graded the yard, and put the seeds down on a day torrential rain was forecast. I was concerned that most of the seeds would be washed away but he swore the grass would grow okay because of the way he had seeded the yard. A few months later some grass had...

Overall it was a painless experience. He came right away, checked out everything, put on a new pressure guage, and said the problem is the water table being very low. He advised to keep pump off when not in use, until after the next rain. Could have told me I need new pump, new well, or whatever...
