Any Mean Green alternatives in EU/Germany?

[hobbyhoarder]

So, has anyone found a good cleaner that's readily available in Europe and works similar to Mean Green?

No I did not.
Having tested the "Mr. Proper" myself in an ultrasonic bath I learned that most of the prints, especially the clear ones got cracks after the bath in water.
I got me a magnetic stirrer for a few bucks at the big A and a 2 Liter plastic bucket with lid. (some kind of lock&lock)
I also do not use IPA anymore just the common ethanol-alcohol "spiritus".
I just rinse my prints still on the plate with a spray-flask and let it bath some 15 minutes in the stirrer. Perfect results.

Thanks for the info, really appreciate it.

Since posting this, I've tried out the method where you pour a bit of ethanol in a small bag, put the object inside, and then place the bag inside ultrasonic cleaner filled with water. I've tried it for a few minutes and it really works great. What I really like about the method is that you don't have to use a lot of ethanol and you can still use the cleaner for everything else, like watches or jewelry, because all the resin stays inside the bag.
