Best Pressure Washer for a 500 sq ft Deck?

Hey everyone! I'm planning to power wash my 500 sq ft wooden deck this spring. It's got some mildew and old stain that needs to come off. I'm on a budget and don't want to overkill. What's a good pressure washer for this? I just need something reliable and easy to use. Thanks!

Hey DeckNewbie99! For a deck that size, you don't need a commercial monster. A 1800-2000 PSI electric model with a 1.2-1.4 GPM will do the job fine. Look for one with a 25 degree tip and a surface cleaner attachment. You can get a decent Sun Joe or Craftsman for around $150. Just remember to use a wide spray and keep it moving to avoid gouging the wood.

I agree with Pete, but if you want something that'll last longer and handle bigger tasks later, maybe step up to a gas model. I've had my 3000 PSI Honda engine for 10 years and it's a beast. But for just a deck, it's overkill. Honestly, rent one from Home Depot if you don't plan on using it often. My neighbor did that and it was easy.

As a pro, I'd recommend not going over 2500 PSI for wood. You'll shred the surface. Also, use a detergent specifically for decks (like 30 Second Cleaner). That'll help break down the mildew without harsh pressure. If you're on a budget, pick up a used electric one from a pawn shop or FB Marketplace. Just check the pump. I've seen good deals.

I'll second Will's advice. And one more tip: if the deck has any soft spots, replace those boards before washing. Also, let the deck dry for a few days before you seal it. I've done this a hundred times. A 2000 PSI electric will do fine. Check out the Craftsman 1800 PSI I have, it's light and easy to store. Got it on sale for $120.
