High Pressure Rinse at Coin Operated Car Wash

[PeteT19640]

Hi all I was wondering if there was something I could use as a pre-soak to get rid of some dirt. Keeping in mind their Pre- soak not sure about.
This is how I wash my car (twice a week)
Where I work is very dusty.
Car daily drive, and outside 100%

I use a High Pressure Rinse > go over with Meguiars Ultimate Detailer > every two weeks, Meguiars Ultimate Spray Wax.

Was looking at a foam gun but cant plug it in down at the car wash.
Is there another way/version of foam gun.

Thank you

You could get a kwazar foam pressure bottle and apply a prewash foam like gtechnic w4 citrus foam or gyeon foam.

Do you use meguiars quick detailer as cleaning with? Or do you use a waterless wash or rinseless wash or a bucket wash before qd?

Thanks for your reply and ideas.

Basically all I do is high pressure rinse > dry with microfiber towel > apply UQD detailer to clean and rid of extra dirt.
I have tried not to use any mitts etc, not touching the car. This works most of the time, though summer here currently, so most of the time is dust etc. Driving through rain etc. probably will be a different story.

Thanks again

You're not using any type of soap at the Coin-Op? If you're not, you really should.

The times I *do* use a coin-op, I high pressure soap, and follow up with high pressure rinse. Sometimes follow up with spot-free rinse.

On rare occasions, when I want a little extra help, I actually use their pre-soap setting, then do as noted above. I find their pre-soap is pretty strong. At least the two that I prefer to visit.

HI thanks

No I don't, seems to be ok very little comes off with the Meguiars UQD probably were I have missed.

I wondered about there own soaps, thought it might be too strong ph etc?
How much does strip the LSP.

I have heard from a painter, he said the water is very good at this one.

Thanks again

I'm kind of in the same boat as you, my car is parked outside all day and night and I work for a construction company so it's super dusty in our parking lot. Just to be on the safer side (because I have black paint), I do a pressure rinse at the coin-op car wash, then do a rinseless wash (Gerry Dean Method) and use a QD as a drying aid. Only takes an extra minute or two to use the rinseless wash and it's a little safer than just using a QD after the pressure rinse. I put the rinseless solution in a 5-gal bucket with a gama-seal lid on it so the water doesn't spill in my car.

You're welcome.

Yeah, I suspect the ph to be "strong" and it will hurt, to some degree, the LSP. The Pre-Soap setting, I mean. During one of my wax comparison tests, I found that the pre-soap did affect the LSP. And so now I only use it when I actually want that stronger cleaning power. That's usually before a polish job, or on a rather neglected car.

I also do like HockeyCrazi with the coin-op / rinseless. It all really depends on what I'm working on and where I am doing the coin-op.

HI guys I did a "high pressure soap" > "high pressure rinse". Came out cleaner.

Does the "high pressure soap" strip the LSP?

Another idea was to high pressure rinse > waterless wash?

With the waterless wash can I use something like Meguiars NXT Wash or something like that diluted or does it have to be a proper waterless wash like Meguiars Wash anywhere?

Thanks again

High pressure won't strip LSP. But the soap may.

Every car wash uses a different brand, different dilution. Your going to have to do some testing.

Really depends how dirty the car is and how effective you LSP is.

I also use the coin operated car wash during the winter. Too complicated to use my pressure washer where I live.

So for me, 2 times out of 3 I only use high water pressure to rinse the whole car off.

The third time, I use the soap setting to wash, then do a quick rinse, then I use the wax setting and I do a final rinse. The soap has to be very acidic or alkalline if it's gonna clean without contact, so you do want to re-apply a LSP after using it. I don't complicate things and simply use the wax that they provide. Probably not a great product but during the winter:

1. The car will be dirty again the next day (2 or 3 days if you are very lucky).
2. There is no sun and high heat to damage the LSP so even a cheap wax should be able to last quite a long time.
3. Where I go it's always super busy so I don't want to take the booth for longer than needed, people already have to wait a while to be able to wash their cars.
