GreaseMaster and Rusteco Gel

Following through the Process

For this part, I diluted GreaseMaster to 400:1 to see how it would work at that level of dilution. You can see in the photo that the inspection plate has seen better days and has accumulated quite a thick layer of grease which has also been baked on by engine and exhaust heat.

This is the result of using GreaseMaster at a 400:1 ratio, sprayed all over and wiped off with rags. Once dry. I couldn't tell there was any residue left by touch, but if you wanted to know how easily it was removed from this application, all I did was use a wet rag to wipe it off. It came off completely and easily (which is necessary for the next step, the application of Rusteco). Click image to enlarge.

Rusteco and Rust Removed

Rusteco and Rust Removed

The inspection plate, while clean, is pretty rusty from 10 years of use and environmental exposure. Because of its size and the fact that the rust isn't very thick, I'll be using the gel. It took several applications, but to be fair the first application I put on was thin. For the next two applications I used a thick coating and scrubbed the rust off with first a scouring pad and then a steel wire brush. In fact, most of the rust was removed with the second application. The third was only used to remove some stubborn deposits and was only applied in small spots. The results were worth the effort. The part was completely cleaned of rust. The dark spots on the plate were a combination of lighting and stains left by the gel that were removed with another application of the gel and scrubbing (I didn't have the opportunity to photo it for this article).
