Restore-A-Deck (RAD) products are specifically designed for the do-it-yourself homeowner wanting to get professional results. The RAD products were formulated by professional woodcare experts. This easy to use two-step system will make the job of bringing your deck back to life easier and quicker. The RAD products were designed to use with a simple deck brush and garden hose for homeowners whom do not have a pressure washer. A deck brush used with these products will get rid of gray wood fibers, mold, mildew and dirt. With that said if you do have access to a pressure washer it can have great advantages to using with RAD products.
If you do not own a pressure washer you can rent one from a local hardware center. Try to get the one with the highest GPM (gallons per minute). The higher the GPM the faster you will be able to wash. The pressure is not as crucial since you should not clean wood with high pressure anyway. Excessive pressure can cause serious damage to your deck. Damage can differ from raised grain and splinters to wand marks that will show up even more after staining.
