I use Evaporust all the time. I set up a parts washer with 4 gallons of it and use the pump and nozzle from the tank to aerate the liquid. The only negative is having to use water and to rinse it and to blow it dry with compressed air. After that I sit the parts in the sun for a few hours to really get the parts dry. If you do not rinse the parts good enough they get a sticky film over them.

 I had read about that. I rinsed them with brake clean and that seemed to work well. Also I think thatf brake clean evaporates water if I'm right. I sure am impressed with this stuff.

I am just impressed that something basically odourless and non toxic can strip rust like this does. I tossed in a couple of heater hose fittings that thread into water pumps and intakes. Those things are always so crusty and they came out beautiful.

I have been using Evaporust for years-does an amazing job-after taking the part out after soaking it overnight I rinse the part in water and make sure it is completely dry then I spray it with Boeshield T-9 Metal protectant(another amazing product)-it dries clear on the part and you don't have to worry about rust and you have the original natural look.You can use T-9 on parts that were never painted to keep that factory look.The only place I can find it is at Lee Valley-very expensive $27 for a 340g spray can-but well worth it!
Keep on Cruising!

Ive used straight vinegar in the past with similar results.
