So I figured since I keep buying crusty Porsches to fix up so I figured an ultra sonic parts cleaner made sense. I bought one big enough to do carbs because well why not right? Any how I have never used one of these things before and was wondering if anyone with experience has a recommendation for cleaning solutions to use? I have researched online and there are a million different recommendations but figured I would start here. Let me know if you have a recommendations. Thanks in advance

I use S100 in mine. It's expensive but does a great job and I trust it with Aluminum, Zinc, and Mag based on prior experience. I dilute it to stretch it a bit further.

I know some of the others like Purple Power available at usual FLAPS, Home Depot, etc., specifically state not to use with Al or Mag and Stainless Steel.

curious what others use.

I've had good luck with Dawn dishwashing liquid and water, sometimes adding some simple green. Idea came from this Pelican thread: http://forums.pelicanparts.com/911-engine-...rt-cleaner.html

This is a bit spendy, but I definitely want something safe for zinc, aluminum and magnesium. I saw someone use plastic and glass containers to help reduce solvent use. Probably will only work for smaller parts, but could be good for latches etc.



I’ve heard dawn is pretty effective, but wasn’t sure how good it really worked. Is this okay on magnesium? For some reason I thought this might discolor it.

Simple Green can cause hydrogen embrittlement so don't use it on hardened steel.

Good to know about simple green. I have done some magnesium parts like my 911's fan housing. It came clean but noticed a high pitched ringing during cleaning. That can't be good.. In the future, will try mineral sprits on mag parts. Been using that on a steering rack with good results. Seems like it would be safer on mag parts than ultrasonic cleaning.

It's actually an approved aerospace deterrent. Just be careful with aluminum and don't sonicate for to long as it may leave marks and cause pitting on the surface

I haven’t bought a cleaner tank yet, which one did you get? Recommend?

Thanks

Hi,
I have been using an ultrasonic cleaner for a year now. I use a solution of Heavy duty Simple green, distilled water, and a small amount of dawn detergent. The simple green will not attack aluminum. Not sure about magnesium.
I got the formula from a thead here in the world. Do a search for it. There are several different formulas suggested by different users.
By the way, I love my ultrasonic cleaner. I have used t a lot. I to bought one big enough to do carbs, but I haven't cleaned a single cat yet. But I have cleaned a lot of other parts.
Good luck and have fun with your cleaner.
Bill.

I use Dawn and simple green. Got mine large enough to do 911 cam towers and with heater. makes cleaning much easier. I make baskets of old window screen for small parts. I find that ultrasonic really makes it much easier to clean. I run part for 20min and then hit with toothbrush and repeat.

I agree Simple Green works well for Aluminum. I tried it on a small expendable Magnesium part and didn't like the result. It appeared to etch it.

Good to know l, no simple green on mag parts, I am going to do a trial run of dawn on some parts this afternoon.

@rcarson25 what size did you get?

30 liter

I tried just dawn and hot water, it worked pretty well for the stuff that was just dirty/fresh greasy, but for the really caked on stuff it just seemed okay. I am going to try some simple green tomorrow to see if that helps for the really caked on stuff. Just going to use on steel for now seems simple green may not be that great on aluminum and magnesium?

Here's a thread on using Pine-sol http://www.914world.com/bbs2/index.php?sho...l=PineSol++carb

I've used it in an ultrasonic cleaner and liked it but don't know anything beyond what is in that thread.

Excuse my ignorance, but can you put "hotter" flammable cleaners in it, like parts washer solvent, or carb dip?
