Don't think for a second that just the high pressure will do the trick...

I spent some time on my car this last weekend and put a fresh coat of wax on it. I'm out of wolfgang (I think I was robbed or something) so I decided to try a few of my favorite waxes to see how they look. Anyway, it rained on Monday and Tuesday, but the rest of the week is supposed to look pretty good. So I figure I should get the car clean tonight so it isn't dirty all day on Wednesday.

I didn't drive in the rain since it only rained while the car was parked, but still... I got tons of waterspots from it raining on my dusty car. I kind of thought that just taking it to the coin op tonight after work I could spray it down and that should take care of the spots. After all, I just waxed it on Saturday and the surface should be pretty slick. Normally I would just bucket wash it and not worry, but I've been in an experimental mood lately and I decided to give it a shot.

The results were not what I expected. I sprayed that car with high pressure for over 3 minutes between the soap and rinse cycles and I thought it would get clean. I didn't dry it with a towel because I didn't want to wipe off any dirt that was missed by the wand. The results were that the car looked nearly as dirty after the water dried as it did before I washed it. It isn't windy out and there is no dust flying about. The waterspots that are left are the same waterspots that were there before I washed it.

I tried taking pictures, but it is dark out and it didn't work very well. It should be nice the rest of the week and my car should get nice and dusty before it rains on it. I'll do the experiment again and take before/after pictures so you can see how little use high pressure alone does on your car.

The bottom line is to not expect the high pressure alone to clean your car. What I ended up doing was just using some Poorboy's Spray & Wipe and cleaned off the waterspots that the wash missed. The car looks good as new now, but it certianly didn't get that way from my poorly spent $2 at the coin-op. It was faster than doing a bucket wash, but it required more than just spraying it off. I had to use the Spray & Wipe afterwards to get it really clean.

Here are my poor 'after' shots of what it looked like after the water dried. Those aren't the waterspots from rinsing the car. I was seeing these spots while I was rinsing the car even. They just required a little more than high pressure to come off.

That doesn't look very clean at all now, does it? It had to be basically washed again after I washed it. If you have different experiences with the sprayer at a coin op car wash without drying the car, then it just goes to show that results may vary. This isn't the first time I've had this happen though. Washing at the coin op is rarely a good way of getting the car actually clean. Typically you have to use that crusty greasy brush to get the job done and that just makes things worse.
 
I concur with your assessment. Pressure washing only takes the big chunks off and does nothing to water spots that are already on the car.

It will be interesting to hear from anyone else that has different results. I would like to know what products that they are using if and when they do.
 
For the record, this is Pinnacle Signature wax on the surface. I have had much different results with other waxes. Since I'm out of my favorite sealant I figure now is a good time to revisit some of my old wax tests and see if the results still hold true. I really wish I had S100 on the car right about now... I hardly even got waterspots in the rain when I used that product. Rain seemed to just rinse the dust off instead of leaving large waterspots.
 
The DIY spray wash and finish with S&W has been my winter procedure for several years now. (Ever since I discovered S&W.:))

I washed a friends vehicle using the pre-soak, the high pressure wash cycle, the high pressure rinse cycle, and the spot free rinse cycle. Close to $7 worth of time. (Not results)
We went over it with S&W afterwards and my MF towel was almost as dirty as if we had just knocked off the chunks and not spent all the time and effort with the pressure wash. There seemed to be a film of dirt all over the car that all the pressure washing did was move it around. Drying right after the DIY wash would be a disaster.

FWIW, I think a great number of the swirls are caused from people drying what is actually still a dirty car. If your drying towel gets dirty, the car wasn't clean.

^^ :bigups Amen to that. I always tell people that if they want to cut down on the swirls then they need to evaluate their washing and drying tools. I even called a local radio station that plays your messages on the air and told everybody that bath towels are for drying your body and not for drying your car. :lol: I leave them a message every once in awhile when the weather is nice and they keep playing them. Traffic and business to OCDetails this year has increased quite a bit because of it too. :bigups Never underestimate the power of radio I guess.
 
I agree. In the winter after a snow and the snow melts and your car gets misted with road salt. I will go to a pressure wash to knock off as much of the salt as I can. I have the same results. I don't use the soap at these washes anymore as I think the soap is to caustic and will reduce my sealant protection. I did not see any difference in how clean the car was using the soap and not using the soap at these type washes. No way would I use the brushes at on of those car washes. I just try and knock a majority of the crud off until I can bucket wash. When I lived in a apartment years ago, I would use those type washes and dry the car, I named those type washes swirl-o-matic. LOL
 
I'm a slow learner. :D I didn't realize until a couple of yers ago, how much scum is really left on a vehicle's finish after a thorough wash at a coin-op. I always follow a coin-op wash with a QEW wash either at the car wash or at home.

Tom :cool:
 
The only method remotely similar to that that may do the job, involves a foam gun :redface:

I've found that if a car is left parked in the rain or * maybe* driven in a very brief and light shower, foaming down, rinsing, and drying the car in sections at a time without mitts( Yep, I can't believe I said it too! ) can get it looking great again. The process is pretty quick. Please keep in mind that IMO, this is only recommended strictly under these conditions and using the slickest wash you have is best. It is in no way a substitute for a "real wash" which involves more washing material, more effort, and consequently, more time.

Of course, any time when consistent/heavier rain and certainly dust is involved, it's going to need to be washed in a typical matter, QEW, or the ways some of the others describe here during winter weather.
 
Same here as Charles I use the DIY for washing the car with pressure then use the S&W for the dry off....I noticed a very thin flim of dirt on the car, and the one that we have here is real good..with the S&W its a dream to get threw

Jeez... what is it with you and this foam gun obsession. :D I might have to give that method a try Bill. thanks for another idea.
 
LOL, I was sure to put the little :redface: beause I was probably literally that when I posted. Yeah, go ahead and see if that works out for you. In my climate, starting in late spring through the fall, it can be very helpful.
