I don't want to spend a lot of money, but I want something that holds up well, and does a great job cleaning. What have you found that works well, without breaking my wallet?


Answer
I bought a "Karcher" brand for just about $120.00 dollars and have been very pleased. It came with two wands and cleans up the most difficult embedded stains. Another feature is the siphon hose. You can apply cleaning agents (not under pressure) and then come back with the cleaning wand to lift up the dirt. Make sure you use "Quick-Snap" hose connectors for leak-less hassle-free hook-ups. I've had my washer for over 3 yrs and am very pleased. I got it at WalMart (Mexico). Good luck

Is there a nozzle that I could buy for a hose that would give me enough pressure to effectively wash my deck?

I do not want to invest in a power washer, and need to seal my deck soon. There are a few dry days coming soon, and I want to clean my deck of dirt, etc.

Are there special nozzles that would make the pressure of the water coming out strong enough to get everything off?



Answer
Hi

The inlet pressure from your household water supply is the ultimate limiting factor on the outlet pressure at the nozzle tip.
Generally household water pressure is 100 PSI at a maximum. While Pressure Washers used around decks generally operate at 800 - 2400 PSI maximum.

So you cannot get anything like the cleaning force of a Pressure Washer from a garden hose.

Now if you do not want to purchase even the lowest cost Pressure Washer from folks like Walmart for about $85.00, here are some suggestions for low cost options that should be an improvement over your typical garden hose nozzle.

Just as pinching off the flow with your thumb at the end of the hose as a kid, the more you restrict the flow at the end of the hose the more hitting force (pressure) and consequently the greater distance the water will travel.

At almost any hardware store or home center you will be able to find a SWEEPER Garden hose Nozzle. These are un-valved short nozzles with small orifices (openings) at the end, which is able to focus the water and let you use them to sweep dirt and debris forward with the water.

Another somewhat more expensive, but still relatively cheap, nozzle that has an even more restrictive orifice (opening) is an Adjust-A-Power nozzle. This nozzle has a rubber tube pinched by ball bearings to create an extremely fine focused stream. This is used by forestry services, where water supply is limited, for fire mop ups. It is also sold by some car wash specialty companies. Most Industrial Rubber companies have access to this nozzle through Dixon Valve.

Keep in mind with the lower water pressure the water flow will be greatly reduced vs. a pressure washer as well. So if the volume of water is needed to clean the surface, it will likely take dramatically longer to complete the job vs. a Pressure Washer.

Good Luck
