And if you need to re-seal your deck, follow my tips, too, to properly prepare your deck surface for a new coat of sealer.

Yes, we all know that dust, dirt, leaves, dead insects and bird droppings can make decks unusable. But with a little time and these pro cleaning tips, you can start enjoying your deck again.

Getting Ready

To power wash deck materials, outdoors, you can either use an electric or a gas power washer. You might find that you have to work a little bit slower with an electric unit, (like a Karcher),  than you would with a gas unit. But you can get great pro results if you follow my tips.

First, clear the way. You need to get all of your furniture and accessories off your deck surface. Pull your chairs, grill, tables, etc. off your deck and out of the way. Nothing slows down your deck power washing faster than if you have move objects every few feet, as you clean.

And make sure all of your electrical outlets, jacks and unmovable fixtures are completely sealed from water.  I always like to cover any nearby shrubs to make sure they don't get accidentally damaged.

Power Wash for
Professional Results

You always need to keep in mind that deck wood and laminates can be easily damaged by using too much water pressure - or putting the nozzle too close to the deck surface. Different materials, including different types of wood, have different hardness factors. If you use too much pressure or put the nozzle too close to the power wash deck surface, it can splinter, fray or "fur". And you don't want that to happen!

I highly recommend starting with the white nozzle. Change from your white nozzle to a more powerful nozzle (green, yellow or red) only IF you need to. (If your electric power washer has an adjustable wand spray tip, instead of interchangeable nozzles, turn the tip so that the water will come out in a wide stream pattern. Not a pinpoint. You can adjust the wand tip to a tighter, more powerful flow only IF you need it.)

Always begin power washing by holding the end of your spray wand at least 3 to 4 feet away from your dirty deck surface. As you see the results, while you wash, you can move the end of your spray wand closer to the deck - but only if you need to.

Here's a good, general guideline for cleaning decks:

If your pressure washer's PSI rating is 2,000 to 3,000 PSI, don't put your nozzle closer than 12" to 24" from the deck surface!

If you pressure washer's PSI rating is 3,000+ PSI, don't put your nozzle closer than 18" to 36" from the deck surface!

Personally, I think its a very good idea to start your power wash deck project in an inconspicuous corner! A steady back-and-forth motion gives the best results. A little bit a practice gives a perfect finish!
