Good points, which is why I no longer do this for head/spindle bolts. And yes, I have quenched the hot screw into alcohol afterwards, which is probably not a good idea, since it could make the screw brittle.

Totally depends on the material if it will become brittle. Just not a good practice to do so and use the bolt again. IMO of course

correct me if I am wrong. Heating and slow cool makes metal softer, heating and quickly quenching make metal hard.
So you should be careful with heat as it may ruin the strength of your fastener.
The below video a nice summary of steel heat treatment. I find the presenter oddly entertaining.

Methyl Ethyl Ketone perhaps?

Don't think it's the nicest stuff but I'm sure it would work.

I use a die to remove those stubborn Loctite build-ups.

To clean a gasser motor, I use mineral spirits. It cleans the oil additives in the gas that has deposited on the motor.

Nitro motors, I use a powder detergent, some water, and an old tooth brush. It looks brand new when done!

An old Crock pot and anti-freeze for cleaning mufflers.

One you have all overlooked is good old white vinegar. It's cheap and you probably already have some at home.

Just leave any gunked parts to soak in that for at least 24 hours, (longer is better if you are in no rush) and then a light scrub with a fine wire brush (or the wire brush attachment in the dremel will do) I've recently cleaned up three old engines and a gunked up silencer with this stuff and it has proved very effective. No need for any heat sources or nasty toxic fumes.

Once cleaned up just dry off and re-oil in the normal way. Not sure how well it works on thread lock but I was able to turn seized screws out by hand after soaking in this stuff.

Worth a try and it won't harm your engine or parts and better still, it won't break the bank.

MEK melts CA glues as well as loctite as I discovered... but dont use this stuff around plastics you plan to keep.

I like the vinegar idea... Wonder if heating the vinegar would speed up the process or make it even more effective against that tar buildup a gasser engine gets on the muffler ?

showing a preference will only get you into trouble, 90% of everything is crap...

If you stay under about 300 degrees for aluminum and about 800 degrees for steel, you won't have any heat treat problems.

I have found that carburetor cleaner will dissolve most anything.
Does a great job of cleaning metals (removing paint too).

If you try the vinegar method, I would NOT recommend boiling the vinegar as the water will evaporate first and the acidity of the vinegar will increase. (Acetic acid) This will do more harm than good as it will corrode your parts as well as the pan containing them and the vinegar. Also the fumes given off (very strong vinegar fumes) are not particularly pleasant and will do you harm.

If you need to go further, try soaking in baking soda after the initial soak with vinegar. Again cheap and not toxic and effective.

This link shows cleaning tools using both the vinegar and the baking soda.
