I recently bought a 3 gallon stainless steel coffee percolator($5.00 at a flea market)one of those big ones like you see in meeting/waiting rooms,and made a neat little parts washer from it.
I put 1/4 cup of Purple Power degreaser and 2 and 1/2 gallons of water in along with a bunch of greasey,oily,muddy parts and plug it in with the power on the lowest setting.The basket that normally holds the coffee is a good place to put small washers and little parts that you dont want missplaced,the percolating action along with the boiling water/degreaser and five minutes later you have some nice clean parts.
I didnt put anything in with rubber or gaskets because the heat would distort them.
I played around with this thing outside until I was sure it was safe to move indoors.Now on rainy days I have something I can do.
Clean up is a snap,just remove the parts(be careful because they will be HOT)wipe the parts down and remove any remaining crude,pour the water out and wipe the container out.
