You can blast water at a spider web all day and not get rid of it with any stream of water.Its just a freak of nature kind of thing I just bought a new gas powered pressure washer to replace my old electric model. I used my old one for these jobs and will use the new one for the same things. 1.My deck I apply a water sealer once a year.There is nothing to remove the sealer is basically gone each year.But I use the pressure washer to remove the dirt and the discolored aged look.The pressure washer removes that aged grey color and brings the wood back to a new look just like new.I have to be careful not to splinter the wood.I use a deck cleaner that helps remove any mold or dirt that is set in.I scrub it lightly with a brush on a long handle not down on my hands and knees. 2.I have white vinal siding that I like to see remain white.On the north side and areas where it does not get sun.I get a green mold if let go.I use the pressure washer to remove this mold.I scrub what I can reach with a bleach and soap mixture to kill the mold.Then pressure wash off the mold and grime.Makes it snow white again.I then spray on a sun and weather protectant product and rinse it off with the pressure washer. 3. I have a lot of grass out here to mow.The bottom side of my mower decks get a lot of grass manure like build up that can rot out a mower deck.I remove the mower decks from the lawn tractors scrape the access out that comes easily.Then pressure wash the deck clean to the metal.I allow it to dry and touch up any places where the paint is gone.I do not blast water into the bearing mandrels and I do grease the fittings to push out any water that could have entered.I have never had a bearing problem and I have had some old well used equipment.Never had a rusted out deck problem because of this practice. 4.I pressure wash my BBQ grill a few times a year.Also maybe a extra time or two.If were having a cook out with friends or family and neighbors.Would not want some guest saying my grill was dirty or greasy.I take out the brickets and grates.Pressure wash the grill grates seperate.Pressure wash the complete grill.Use a degreaser allow it time to work.Then pressure wash it clean.Its amasing the grease dirt and grime that comes out of these things.Its a wonder people do not get food posioning Yuck!Does anyone really take there grill apart and clean it after each use like they recomend?If I had to I would not grill out ever. 5.Outside lawn furniture gets dirty grimey and can get moldy.So I pressure wash it down a time or two a year.I scrub the cushion and things with soap and then blast it away. 6.My garbage cans get nasty inside.So I pressure wash them out a few times a year during warm weather. 7.I wash off the windows outside on the second story with a blast of water a few times a year.Does not replace hand cleaning them and removing them however.But im not doing windows on the second story very often anyway.OK maybe im lazy but thats to bad I do not look out of them much these days up stairs anyway. 8.Window screens get nasty.I take them out and pressure wash them you have to be careful.Unless there the alluminum screen wire type.But a srcreen is like a filter amazing the grime that washes away.I admits a garden hose is maybe just as affective however. 9.I forgot to mention I have high concret block foundation.Thats looking a little shabby with mold.I plan to see if I can brighten the blocks up a little this summer. 10.Garage floors you just can not beat a pressure washer to clean them.If I ever get a garage with a concrete floor I will have this use also.My floor is gravel old garage. 11.I have a inside Sheltie dog.But during warm weather he likes to spend time in his 10x12 kennel that has a rubber mat perferated floor.That has a poly plastic dog house.Hard telling what kind of critters fleas bugs live in there.If not cleaned disinfected.So I use it to pressure wash the flooring and the dog house.I use bleach and soap on the dog house and pressure wash it clean.So he does not bring who knows what into the house. Thats about it for me.I might find more uses and have better results now that I have a gas model.More PSI and GPM and no more stringing the electric cord and standing around water.Should be a improvement over my old 1600 psi electric model.My new one is only 2500 psi and 2.3gpm but I do not want to splinter wood and cut or blow holes in my siding or get the back side wet.So I think I will be happy with the results as I was with the old one. You do have to hand scrub just about anything you do with a pressure washer.To loosen it up.But it does make the job easier and with better results.Just like washing a car you still have to loosen the grime before its really clean.A pressure washer and soap alone will not cut it.If it was that powerful you would not have any paint left and I bet it would still not be clean.

Thanks guy's for your opinins. I appreciate it and must say I'm rather surprised as well. However, to each his own....I to have a little Coleman 1300 psi electric for twenty years and it's still going strong. It's a nice little washer for what it's intended and that is....small tasks (washing off lawn and patio furniture, etc.). As I mentioned I tried out my son's new Craftsman BS7hp, 2500 psi with 2.3gpm machine and wasn't that impressed with it's performance. If your friend drilled a hole in his asphalt drive he muct have become intranced from watching the spray and forgot he had to move that wand around alittle and check out which nozzle was mounted in the wand. I purchased the new All Pro with 13hp Honda, 4000psi and 4 gpm capabilities and can't wait to use it in the morning. My experience as a woodworker and homeowner for over 45 years has proven time and time again that when it comes to power tools more power is always more desirable than not enough. IMO it's always worth the extra money + it makes for a much more pleasant experience.lol Again, thanks for your input. JimK

You have to \\"nozzle\\" down your pressure washer\\\'s output. Professionals rarely go above 1000 psi when washing anything. Get yourself some Outdoor Clorox and apply with a pump-up sprayer. The Outdoor clorox has some sodium hydroxide content to it as well as some surfactants so it will work a little better on dirt and stains. The key for you is to change the nozzle at the end of your wand to a larger orifice version to reduce the pressure. Unfortunately the people at the box stores like Home Depot will just stare at you blankly when you ask them for a 4010 nozzle that is quick coupled to fit your wand. Go to a pressure washer dealer. They should be able to set you up.

There is nothing about electric vs. gas that makes a PW "last". There are short and long lasting ones of each. There are various materials for the pump and various ways to make electric motors or gas engines. For example we have the industrial version of the one I recommended above at one business. The specs are about the same but it costs about $800. It is worth that if you are using it 20-30 hours a week like we do. We have another electric that is used almost every day for more than 15 years in a commercial wash rack for trucks hauling food. A decent universal electric motor will last as long as a decent gas engine. An induction electric motor will last about forever but will only be in electrics starting around $500. The advantage of gas is portability and the possibility of higher power. If you want to match the power of a 5hp gas engine unit, you can't quite get there on 120v power. The big disadvantage of gas is reliability and maintenance. Modern gas does not sit well at all. This means you have to buy better gas for about $20 per gallon or deal with draining or using stabilizers. There is still other maintenance that is required. It isn't that one is better than the other. It depends on your use.
