Default Dry Ice cleaning?

I'm the lucky new owner of a 2018 GT3 touring with 22k miles on it. It was daily driven by a 70 year old gentleman. He traded it in for a 992 GT3 touring and will daily that. Legend status for sure.

Anyhow, I have an appointment scheduled for March 11th to clean up the car with the main focus being on the bottom side.. I have high expectations and expect a like new under carraige is in my near future.

These guys are professionals but just curious if anyone on the forum has had this done? Any tips?

I'm assuming the carbon ceramics will be fine but that will definately be a point of concern. As will removing the wheel properly, putting them on properly.

I'm also going to have him do some rubber trim pieces (roof seals) etc. Where the owner had some bad details done and wax residue currently resides.

Would love to hear your thoughts.

Seriously?! I personally don't care what the undercarriage looks like: it can be pristinely clean, but after a mile drive, it looks like any other undercarriage. If you're doing that, I suppose you should clean your brake pads after each drive as well. . .

I blast my cars with OPR. Seriously, much better results. I'm a 70 year old gentleman too. Only drive the GT3 RS a few miles on weekends. 7 sessions of 20 minutes per day. Hell yeah!

Dry Ice is a good way to get all the crud and rocks out of the panels, cracks and crevices. These new cars are not covered in cosmoline, so they don’t get black like the older cars, but if you pull the plastics and blow all of the nooks and crannies then put everything back, its a good maintenance step. It is perfect to get the wax off plastic and rubber and clean up all the details. Also have the door jambs done, no better way to get them clean. Just make sure they are using the right equipment for automotive. Industrial blasters can be too harsh for the process.

Good luck!

Don't worry about the guys advising against it because it's just a car, they just aren't one of us insane people.

There is nothing like getting your car up on the lift and having it look brand new underneath. Check out the AMMO NYC and Obsessed Garage YouTube channels, they both have videos detailing the process.

I'd probably ask if I could take the wheels off myself, just to be safe.

I guess "keep the shiny side up" doesn't mean much anymore.

I have a few customers that use Dry Ice cleaning as a way of getting a car that is new to them back into showroom new condition, regardless of mileage.

Here are a few pictures from a low mileage GT3 that I did recently. All plastics including the fender liners and underbody panels were removed in order to clean every inch of the underbody and all crevices. It was absolutely showroom fresh when it was finished.

Let me know if you have any specific questions about the process and how it would relate to your GT3.

I'll have to admit, it does look showroom fresh, but perhaps you'd find more interest in the Concours section of Rennlist.

I'm not faulting them for not knowing the full situation. This car was daily driven in Chicago. If anyone has ever driven through mid western winters they would fully support a dry ice detail.

I am driving the car. It now has 22k miles on it, I also drive it hard. It redlines at 9k for a reason.

And I'm hoping to make it the highest mile and cleanest Touring in the country. Yes I do intend to have it both ways but it won't be easy.

What great results. So did you clean the fender liners on the car first, then removed and tackle behind it?

Also how long did it take you. I warned the shop this could be a 16 hour job. He has me scheudled for 8 hours at the moment.

Did you remove the rear bumper as well?

GREAT POINT! I initially didn't want them removed but knew to get all the salt off the car and clean it properly they had to be removed.

Yes I'm learning the process and have ordered all the tools. After doing my research It looks like:

Loosen and remove the nut only with no load on the suspension

Install the center lock wheel guide pin so no $6000 rotor is damaged

Install is install center lock wheel guide pin

Use the Catrol alum grease and lube areas

Tighten to 443 ft lbs. Loosen 1/4" turn, retighten.

Got my lightly used Snap On 3/4" torque wrench coming!

Am I missing anything?
