When it’s time to clean your wood deck in preparation for refinishing, a chemical deck brightener applied by hand-scrubbing may not do the job of deep-cleaning, but a power washer will. Often a pressure-washer can effectively clean a deck with just plain water. But a pressure washer can ruin your deck if it’s not used properly. This is a tool that is powerful enough to etch brick, but in the right hands it can also be gentle enough to wash siding. If you use it with too much jet pressure or place the tip too close to the surface of your deck, you can deeply etch the wood and cause the fibers to splinter.
There are three basic steps to doing it right:
- Pressure and Tip Selection
- Power Washing
- Sanding After Washing
