de rusting parts
« on: November 20, 2018, 11:44:09 pm »
As a test I filled a 5 gallon pail with 4.5 gallons of white vinegar then submerged my rusty oil pan for 2 days at which time we took it out and used a nail brush to clean the treated metal . Once again I placed the pan in the vinegar for 1 more day.

The results are quite dramatic , pristine bare metal remains.

My first thought was to media blast but that would run the risk of sand getting trapped and causing problems later.

This idea seems to work better than my $100 jug of evapo- rust and cost only $10.

My next test will be all my rusty bolts , nuts , washers ect.

     If vinegar works then I'd suggest trying citric acid. It needs to be added to warm/hot water. Not very active at room temperature & doesn't have a strong smell.  Comes as white granular like sugar. Very common, can be bought cheaply thru restaurant supply stores, EBay carries it or as a dishwasher additive named Lemishine. Really great at cleaning water spots off of dishes & flatware. If you have hard water, run a load or two using it instead of soap.

Nice! Vinegar is cheap. You will notice that as soon as it dries,flash rust starts in again. You can eliminate this problem with a product called Phix. Comes in a spray bottle and available at paint and body stores. Leaves a nice gray finish that remains rust free for a long time. Easy to paint when you're ready.

I use a Por15 product , it's a de-ruster but can be used as a metal prep so it just gets brushed or wiped on and after a few minutes rinse off with water. This takes care of the flash rust for a while.

Interested in the Phix product , seems like a good option.
