note pictures
I didn't see any before pictures. Overall, though, it's interesting. The cleaning he's claiming is more in line with what I imagine it should look like. The heavy black varnish is still there, but the moving parts are clean. No sludge. Definitely not proof, but interesting nonetheless.

In the old days (early 1950's) we used to use ATF. But that was when it had whale oil as one of the ingredients. Has not been there for decades. But same principal applies. You need different chemistry with lower surface tension.
Unfortunately, if you built the varnish with synthetics, where can you turn ... KREEN from Kano Labs will definitely loosen deposits. It's the most aggressive cleaner/solvent you can run in oil while driving. Anything more aggressive will destroy the lubricating qualities of the oil. One can per oil change, or 8 oz per if you are a bit concerned, will get you some visual results in about 5 or 6 oils changes.
I prefer the next slightly lesser solvent/cleaner BG109 (EPR now) which will do the same job, but may take 10 oil changes to do it. I've got the time, I'm just driving it anyway
If you did the dirt/deposits with conventional oil, something like Pennz Plat will do as good a job as it's an alternate chemistry and has lower surface tension. Just what you are looking for.
But baked on hard deposits prolly ain't coming off with anything short of a machine shop and boil tank ...
Are there any before/after photos for Kreen? It seems to be a loved cleaning agent here.
The Volvo I'm hoping to clean up was always, as far as I know, filled with strictly conventional oil. I've been using M1HM since I got it.
