You can get Facto AT30 from Swish USA. It is water based and comes in a 20 liter pail which will last you a long time. They (at least their home office) now know how to ship it; a couple of Rennlisters now use the product as well.

Bar none, the best degreaser I have come across and used in my 28 years of using the stuff. And it works out to far less per liter than most consumer grade products.

Thanks to everyone for your advice. Can't wait to get home and have at it!

And of course I am going to get in there with my bare hands and some rags to do the nitty gtitty. That's half the fun for me.

I will do my best!

I have read that simple green is not good, it does cut grease, but is otherwise not good for the aluminum or the rubber.

P21S is highly recommended, though I have not tried it myself.

Has anyone tried P21S Total Auto Wash? A couple of people recommended it.

While the engine & engine compartment of my Targa were extremely clean thanks to under 18k miles and care by previous owners, there were a couple of places that needed cleaning. This P21S product seemed to work well. And, it doesn't stink like GUNK.

Mine's pretty clean, but I'm gonna wait to Dec when I drop the motor for the clutch, for a real cleaning.

I like Opt Power Clean. Lot's of pro detailers use their stuff. It's 20% off till 10/10 at this link:

Fikse recommended (the old Fikse, at least) using Simple Green to clean their aluminum wheels. I have never had a problem using the stuff with my wheels.

Hi Ed,

On my C2, it isn't necessary to drop the engine to do the clutch--tranny only.

Way back in the days when I was a service tech, we had a saying..."if it don't fit...force it...if it breaks...it needed replacing anyway"...

My 993 has never really gotten dirty enough to need a "spray down" cleaning. But I have other cars that have...and I do the same as a few others...spray Simple Green on it...then hose it off gently. However, one thing I think is a good idea is to never start the car after the spray down...until it has had plenty of time to sit in the sun a dry...because any electrical parts that may have gotten damp...stand a better chance of survival if they have dried out before the electricity is applied.

I will add, I have only read that Simple Green is not recommended. I don't recall where exactly I read it, but probably on a post here someplace.

I don't use it frequently, maybe once every two years if that, on parts of the engine , and use plenty of water to wash it all off. If there are ill effects on the aluminum, I have yet to see them

Black Magic 2 in 1 Engine Shine. That's what I use and you can get it almost anywhere. It says on the can, safe for all engine parts. I'll say I am very impressed at how well it works.

Just going by what Travis at Fikse told me many years ago. The stuff never affected my rims (anodized centers and raw, polished lips). Their cleaning protocol may have changed with the sale of the company.

I think SG is fine, as long as it is rinsed off well. It can be caustic to Alum, if not rinsed-maybe more so in full strength.
