Which is better for what duty? Is hot or cold better for vehicles, side walks, vinyl siding, windows, brick buildings/houses, wood, removing paint/stains, etc. And also- what is a good PSI for these sort of things? Thinking between 2000 and 4000? What is best..? Thanks!
YES!!! I'm sorry I do mean pressure washers!!!
Answer
Are you talking about a pressure washer? There are pressure washers used primarily by commercial companies that do in fact provide hot water, but these are very expensive. Regular cold water pressure washers come in a variey of psi levels, usually starting in at around 1,500 psi for an electric one, and around 2,000 psi for a gas powered one. The higher the psi, the more cleaning capability it has. The trick is to use a chemcial designed for the task you are doing, allow the chemical to "work", then rinse it off with your pressure washer. Far too many people rely on water pressure alone, which (depending on what it is that you're cleaning) may or may not do the job. For example, for vinyl siding, soffit and fascia, etc. I've used a mixture of bleach and liquid Spic 'n Span in a pump-up garden sprayer. Put a good amount of each in the sprayer, slowly add water then apply the mixture to the house. Allow it to work for 10 minutes or so, then follow up with a good pressure washer rinse. This kills the "critters", mold, mildew, and removes the dirt etc. For my painted concrete driveway, and brickwork around the house, I use "Rust-Aid" which is available at Home Depot. Apply full strength, allow it to work, then blast it off with the pressure sprayer.
