    Want to find parts online.

    I have a Karcher hds3205 BE unit that I want to get parts for but can't seem to locate a supplier online. Karcher got into the portable homeowner type units big time and a search on ' Karcher parts' dumps out a bunch of useless suppliers. It is interesting that some of them offer owner manuals...

    Can I peel the paint?

    Gauging an x-jet

    I just bought an m-jet, adjustable x-jet. How do I gauge my proportion when using the x-jet without inserts? I have a Karcher running 3200 psi at 5.2 gpm. Do I simply drain a 5 gal bucket of water for 15 seconds and see how many gallons of water I've sucked up times 4 then divide that into 5.2...

    Pipe preparation for paint

    I've got a shot at cleaning some pipe in preparation for painting. The customer says no soap because it leaves a film which may effect the paint. 225 degree water only is what he wants. I have heard of a soap that is used for car painting prep. I'm told that it bonds with the metal and gives a...

    Concrete cleaning

    Does anyone have experience using a concrete cleaner called Rekrete? It is a dry powder that contains an enzyme that causes a reaction whereby the hydrocarbons are converted to carbon dioxide. The maximum effect is supposedly achieved after 1 week. You simply sprinkle it over the stain and broom...
