how to remove oil from fasteners without using water

[ht3jyx]

we are a job shop, one customer requires us not to use water (cold or hot, with anti-rust agent or not) to clean parts, because the metal parts is very sensative to get rust. the parts after process normally covered with machine oil. is there any way or equipment to remove oil. someone suggest a powerful blower might do the work. any one has such experience?

thanks,

It's probably frowned upon now-a-days, but diesel works pretty good - alot better than water.

What type of oil? How about organic solvents to remove organic contamination? Common choices are methanol/ethanol, IPA, MEK, trichlorethane, methylene chloride, among others.

Safety-Kleen part washers are often the chosen method.

quench oil from heat treating.

Xylol to remove the oil, acetone to remove the xylol.

And then immediately coat them in oil to prevent rust.

Vapor degreasers work really well.

Vapor degreasing does work really well. Do you have a plan to protect the clean parts after degreasing? Immediately pack in vapor paper? If the customer is ultra-concerned about corrosion, you will not be able to bare-hand handle the degreased parts.

an organic citric acid solution (i think & i do not remember the product name). i get the stuff from the local ACE Hardware store to clean snow machine engine (under the hood) an end of year. stuff works great at removing oil and other junk (liquids and debris). just spray and wipe.

good luck!

And what solvent carries the citric acid?

Just saw this on The History Channel: Clean the parts with a high velocity stream of dry ice particles. Takes mold off books without wetting the paper!

Change the quench oil to a "dry to the touch" quench oil. Chrysler made us switch a few years back, and it works great.
