Q: Just received my new Karcher 5.740 pressure washer. What's the best way to use this for car washing? I've never used a pressure washer for this purpose before. Thanks!

Worthless
I bought pressure my pressure washer and then I purchased this soap in hopes of easing the task of washing the car. This soap is no better than plain water. So I'm back to a pail and hand mit to get my car clean.

Now I use the pressure washer to hose off the driveway and the house after I scrub the house with Simple Green green soap. That's really the best all around soap to wash greasy stuff and vinyl siding. Then I rinse it off with high pressure water.
Cons: Low Quality, Unreliable, Expensive

Normand,
I'm sorry the Karcher vehicle detergent didn't meet your needs. Pressure washer-safe detergents are formulated so they don't damage the seals and surfaces in your pump. For tough jobs your 2-step process is the most effective.

We carry Simple Green Pressure Washer-Safe soaps for a variety of surfaces. It's concentrated; so it needs to be diluted down thin enough that the flow of water going through the pressure washer can siphon it up. One gallon of Simple Green makes up to 11 gallons of detergent.

Nice & Compact
The K2.20 Is Nice and Compact, Good For General Use... I Use It For Car Washing.

the Only Issue Is the Soap Feed Tube Hangs Free With No Soap Dispenser Supplied. However Is Is Easy to Make a Holder If You Want to So When You Move the Machine the Soap Follows.

Other Wise Out of the Box You Put the Soap Tube Into Your Bottle, But If You Move the Machine You Have to Move the Soap Bottle Also. Overall This Can Be Modified by Most Men For Ease of Use.

I Am Using the Machine Off a Power... more

Cleaned Patio In 30 Minutes
Started on 2nd pull. Came with no damage.

Seems water hose won't keep up with pressure washer. Have to release trigger for about 5 secs. between bursts. This seems to prolong the cleaning cycle using the green tip. Although I only used this washer for about 30 min. it it cleaned my patio very well.

Don't know if I need to do something to allow for continuous cleaning or this is just what happens with a 3100 psi washer. I didn't have this problem with my old 2200 psi washer.
