Review on Gunk SC3 Super Concentrate Degreaser - High-Performance Cleaning Solution for Industrial Use - 1 Gallon by Deonte Bates

I enjoy restoring mechanical equipment from the early 1900's such as adding machines, sewing machines etc - and one of the challenges with this type of restoration is removing fossilized, hardened grease and oil. I bought a 10 liter heated ultrasonic cleaner off eBay (for about $120) and followed the directions on Gunk Concentrate to fill the cleaner. My petrified 1930's arithmometer came in and out came a great degreased machine ready for restoration. I went away. Gunk in an ultrasonic cleaner that comes with a lid to prevent fumes and splattering. I recommend this product for any type of metal degreasing. Haven't tried it and probably wouldn't recommend using it on anything non-metal - just follow the instructions and you should get the same results as me.
