  I watched a video recently of a guy using a machine that utilizes  high velocity air and mixes pulverized dry ice in the air stream.

 

That method is also used to clean grease from cooking apparatus in commercial kitchens.

What is toxic about the water solution and the iron from the rust?  I all comes from the earth to start with. 

Oil comes from the earth too,  but you better not be dumping your oil on the ground!

What's wrong with a good old sand blaster?

Not everyone has one or access to one, so I was trying to share a method that many people that don't have all the fancy equipment could use. Noting is wrong with a sandblaster  if you have one. but if you didn't and you only had a handful of things to do you and don't see yourself going out and buying a mess load of specialty products to do a few jobs, then this method may be of help to you.

I made an electrolysis tank out of a 5 gallon bucket using information from a thread on this site. Works great. I've also used the plain white vinegar soak. I've never heard of mixing it with molasses before before but it's always nice to have another weapon to use in the war on rust. Thanks for the information.

But we are not talking about oil here are we.  Water, washing soda and the iron residual from the rust.

 

No big expense to this either.  Who don't have a plastic bucket and battery charger around.  Scrap pile has the rods along with a little wire.

 

HF has sand blasting guns at very reasonable prices.  I picked up a nice set up at an auction for $5, 2 guns, hose, holding pot for the media and all.  Yes, one needs the air compressor to handle the volume required.  I picked up an upright with twin cylinder, 220V, at least a 60 gal. tank and a box of new parts for $100.  Guy could not get it to pump up above 80 lbs.  Got it home, tightened the belt and lined it up right and ran it every since.  Been 4 years ago.
