New Hampshire CMP Barn 2011- 2012 HUP Overhaul

[Phil Waterman]

Hi Stew

I have used washing soda in the past with power supply to derust parts works pretty good.

But using washing soda hot at a higher concentration does a pretty good job of softening multilayer of paint and clearing some of the rust. Was reminded this morning that if you let paint on a part cool off and dry out the paint gets surprisingly hard again.

Really should do some controlled experiments to see what concentrations, at what temperature work best. But that will have to wait until I have the HUP back together. Right now my priority is to gets those last bits that I didn't clean when disassembling cleaned and repainted so they can go back on the truck.

Cheers Phil

Hi Phil
I have a 5 and a half foot x five foot high tank that I use and then use my welder for the power supply with 2 quarts of soda from Home depot
and I can remove rust, paint , and what ever else is there in a few hours.
Just make sure the connections are right or your steel ages and disappears into rust. For cleaning the roofs on the cabs I just lay down a plastic sheet , set up some blocks around it and fill with water ( like a mini pool) and Soda and the welder and it cleans them up real quick
All you need to do is hose the parts down and brush them off
It has worked for me for a lot of years
