Pressure washer...

Do any of you use a pressure washer to clean your mini?

I was thinking of getting one but most of the ones I've seen have pressure around 2500 psi. That just seems a little too much for cars as it would probable push past the weather stripping.

Anyway, if you use one, what model is it and how do you like it for washing your vehicles?

Thanks...

You can adjust the output of a pressure washer a few different ways. One way is just to stand farther away from the car, lol. Pressure washers will mist the water on the car that feels like soft cotton. Put the tip right up to a paint panel and it will take it off immediately.



Pressure washers are great for removing really hard to remove stuff in wheel wells, on wheels, and even paint. I don't let my paint get that dirty so I find a pressure washer mostly unnecessary unless it's like my Nomad.

Professional mobile detailers use pressure washers because they have a huge tank of water and no way to get out..so a pressure washer is needed.

I used to have a Karcher electric pressure washer and it worked fine, though after a year, a seal burst inside and leaked water like crazy so I had to stop using it. I don't miss it.

I have a gas engine pressure washer at the shop but I don't use it, except to clean off the floors. It's noisy! But these work great with a foam gun to add foam to a car if you like that.

Some very old pix (2005) of me washing some cars with that Karcher




An early experiment with foaming...used way too much soap to be practical


An experiment I did with making a self contained water source for the Karcher using a 2 gallon(?) bug sprayer, the idea was to pressurize it by hand, and feed it into the Karcher so I could wash a car without carrying tons of water. Just wanted a small water source. It worked but eventually I discovered the Nomad which worked much better.

As OctaneGuy said, they usually have multiple setting that are in degrees of spray. 0 degrees is a straight stream. I already had one to clean off the driveway. On the highest setting (0 degrees), it puts holes in bricks. I obviously don't use that for the cars. 15 degrees is fine though.

It's great for blasting off the brake dust, bugs and bird poop :-)

Mine also has a soap setting. There is a separate tube that drops into your car soap bucket. You have to cut the soap with water or it's too foamy. It sprays a lot of water with soap on the car.

Thinking about getting a pressure washer to wash my 'soon to be born' MINI JCW CM. I have 2 options (2000 PSI and 1600 PSI) that I am considering. Any issues if I get the stronger 2000 vs 1600? There is a 2300 option out there (these are all electric) but I think that is unnecessary.

Also, can anyone recommend a good foam cannon/soap?

I do NOT recommend a pressure washer for a car .... the average pressure washer can generate enuf force to take the paint off ......

Unless you are familiar with pressure washers and how to use them I say learning on your car is NOT a good idea .....

Here's a catalog page from a major car care company. Nowhere do they show a pressure washer for good reason. Richard Lin/Octaneguy has years of detailing experience and knows just how to do it. Don't learn on your brand new MINI.

PS: I would recommend you contact Richard at http://www.showcarperfection.com/ and order a jar of Black Wow. There is nothing else on the market that keeps the black trim looking black.

I read somewhere years and years a go that a pressure washer would drive the dirt into the finish and embed it. That seemed to be the case when I went to wax my '69 Datsun 2000. Since then I have always used a gentle stream even with a garden hose and the results have been what I want.

If you (OP) are worried about embedded particles, that's what clay bar is for.

Pressure washer, flow control, not that difficult to use. Foaming action is pretty fun to watch. My pressure washer doesn't have the power to run a foam gun so I rarely use it.

You might be pleasantly surprised by the foaming you can get from a regular hose and a foam gun. Maybe it's not a dramatic "Foam Lance" but if the goal is to pre-soak the car with lots of suds this works great:

Amazon Amazon

I'd save the money that pressure washer costs and use it for something like decent brake pads or a Dinantronics Sport module.

A bigger pump pushing water through a small hole gives you the pressure. Most car wash places have large pumps as there are usually several bays involved so the pressure is regulated through the hole in the tip of the wand. I wash my car by hand but when on the road will stop by a car-wash to clean up a little and also spray into those body joints where dirt hides.

I use my 1600 PSI washer washer on the suspension, brakes, lower engine/transmission and underbody. I did use it on my son's engine bay to clean the painted areas, do not like to spray the top of the engine area around all the electrical connections.

I use a pressure washer most times I wash the car. I also use a foam cannon with it. The paint has not been damaged.

If you have to use it, just make sure you dont get too close to the paint. Some of the gas powered ones are so powerful they can blow off the paint. The lower PSI electric ones and holding the sprayer 2-3 feet away seems to be ok.

Foam cannons through the regular hose are safer.

Doubt you could shoot foam from a PW cannon and do damage to your car. Garden hose foam cannon works but nowhere near as well as the pressure washer ones.

I went the route of using a PW and a foam cannon vs standard hose. I tested it on my Prius (soon to be traded in) and honestly I don't see what all the fuss is all about. As long as you are being smart about it, not holding it too close and using a safe(r) PSI, it seems fine. Plus, now I have an excuse to pressure wash my windows, grill, house, etc.

Using the foam cannon saves so much time!

I use a 3000 psi pressure washer to clean the bottom of my boat, it'll take off barnacles and bottom paint. I imagine it would strip off any chrome trim and emblems on the MINI pretty quick.

I own a Mobile Detail Service company, we use 2500 psi PW's along with Foam Cannons. Pressure coming from the Foam Cannons will never hurt your paint. We also use a 25-35 degree tips on the pressure washer to rinse the cars, it gives you more misting than say a 10-15 degree tip that will cut in to metal and paint. You actually use less water with a pressure washer than a garden hose, which helps save water.
