Brushless car washes are fine. I do it all the time. Also, the spray hoses to the wheel wells and undercarriage are fine too, just don't over do it. Nothing will be hurt in the front, but take care in the rear, and in the rear wheel wells.

Note - if you are part of the concour crowd, don't go to any car wash. Do it at home with your own garden hose, low pressure and all of the other good OCD stuff to keep the swirls at bay.

Touchless is fine, just keep in mind the way they get your car clean is by using very strong chemical cleaners and soaps, so it will most likely strip your wax. However, if you ever have to drive your car in salt or do regularly be sure to get it with the undercarriage wash and then just reapply your wax later. You could also get some of it with a pressure washer at home but due to these cars being so low it doesn't work as well. Not affiliated in any way and I don't have one but if you have a Karcher Pressure Washer you can pick up one of these. https://www.kaercher.com/int/accesso...-26425610.html

Check your local car coin washes. Some have spray systems in the edge of the floor of the bay that start spraying the undersides as you drive in slowly. Check that they use fresh water. Unfortunately, the one near me recycles its water, so salt in solution is re-sprayed on the car.

I do two things after the winter salt is gone and washed off the roads by a few good rains.....

1) Drive fast through big puddles. I really do this and it quite entertaining.
2) I have a soap dispenser spray thingy I attach to my garden hose. When I do my first wash of the spring, I spray higher pressure soapy water at stuff in and through the wheel wells.

I clean mine by driving 100mph in the rain. Ha.

wash them anytime with simple green or strong car wash and a rag. If you have time take them off and wash out the sand and dirt and gravel

Without a lift this is hard to do. Are you looking to remove the panels and then clean because that will allow you to access and rinse better. You could get the car up on jacks but you will end up soaked because you will have to lay on the ground. Even with my lift I get pretty wet. Check around because I know there is a company in the DC area (northern VA) that will do this.

Be very careful with automatic car washes. The tracks that your wheels ride in to advance the car are not really made for our wide and low-profile rear wheels and will scratch the heck out of them. The tracks are low enough where larger SUVs with fairly wide tires the wheels are still above the track line and it just rubs the tire, but not on a 911.

I'm with Petza914 - My issue is 275 tracks and my 3oo+ tires...
Plus the time it takes to line up, 20 minutes or more, and the lady in front of me doesn't have a ticket, and just quickly runs in to buy her wash, then forgets her purse in her abandoned car and has to run back to pay.

so i also heard that the touchless car washes are not good for the cabriolet soft top? man o man, i getting too OCD

isthar

The concern is that the high pressure used will ... let's just say "stress" a soft top and/or water can find its way in/through seams or other points that usually natural rain would not reach. I suppose if some day birds have a field day over your soft top I'd rather just use a touchless car wash than do nothing to it...

guppychao

then all the bird poop residue juice will find its way though the seams too

thanks for all the recommendations!!! super appreciated

From someone that rides motorcycles, they build up a lot of grease, debris and bugs. I def recommend S100.

I've cleaned my Supra and plan to clean my C2S the same way. If you don't periodically clean those areas, the harder it is to clean later on. I'll take all 4 wheels off and clean the fender wells, brake calipers every month so that it doesn't build up and bake on.

-Put the car on Esco jack stands
-Lay down some tarp underneath the car
-Use a creeper to move around the floor
-I use the HF coveralls and eye protection https://www.harborfreight.com/white-...rge-66348.html
-Start in sections; front bumper to front axle, mid section, rear axle to rear bumper
-I use a combination of soft brushes and sponges to help agitate the areas
-Light water pressure to wash away the grime
-Air compressor to help dry the area and relieve trapped water in tight areas

I've been thinking about buying a water broom. They make them to fit pressure washers and garden hoses. Might have to buy angle fittings to make them spray up instead of down and they are pretty cheap on amazon. (some under $50)
