ultrasonic gun cleaning solution

[seven-up]

I bought an ultrasonic cleaner a few months back, but have not yet used it. I'm not to keen on using a concentrated solution with water. So, I'm wanting to know what cleaning solution do ya'll use for your guns?

I use this. Works great and a gallon will last you forever.

I use ballistol. 8 parts water to 1 part ballistol.

Do not put anything aluminum in it. Just in case you didn't know that already.

Why not?
