I use paint thinners. It seems to work fine.

and none of the other solvents damage the wing scales, or mess up the setting job?
right now acetone seems to have no drawback. It turned out much better than I expected

How do you dispose of the acetone once you've exhausted its ability to draw out any more grease?
Thanks! Jim

Leave it outside with the lid off and the acetone will evaporate fairly quickly.

Do the hard-core lep collectors degrease all of their specimens, or just some select ones for display? The photos that I've seen by different collectors of their acetone degreasing processes look as if you couldn't process a lot of specimens concurrently. One night's black-/MV lighting would take quarts (gallons?) of acetone? Thanks!

This hc collector does it just when needed....surely not to all.

I'd only do the ones that have noticeable grease stains
Well like this S. diana

I agree, I would only do grease stained ones, but there are a couple of Moth families that will grease up overnight! I would ALWAYS degrease Hepialidae and Cossidae as a matter of course. Dave

I was fortunate enough to collect a perfect specimen of Morpheus clenchi this weekend. Now I am worried about it greasing up. Any advice on whether I should remove the abdomen and degrease it in acetone, degrease the entire moth in acetone, or just spread it and hope for the best? If it does grease up after spreading, how effective is degreasing on Cossidae? I have had hit or miss results on other specimens.

I only collected one specimen here in Canada and about 20 in Thailand but they all get greasy and I mean like you would soak them in oil for few days. They were all previously dry and papered but within couple of years before I had a chance to mount them they all were perfectly oiled. I must to soak them in acetone not one time but few times each specimen to get rid of all oils. I would probably spread the specimen and wait at least few months to see how bad it will get, but most likely it will.

Just want to add that each time you should use new acetone, however to save some, the last bath I was using for initial bath of the another specimen as the acetone always turned to yellow brown after first soak.

Now is an old old thread. It was started in 2012.

You can also re-distill your used acetone to recycle it. Just remember acetone is a very flammable solvent and you should use a heat bath to avoid direct heating!

Leave it for professionals

There is another thread on this where degreasing was extensively discussed. FYI
I have used acetone and isopropyl alcohol with far greater success from alcohol. FAR greater. A specimen that had endured multiple acetone baths was submerged in alcohol and immediately the brown oils were pulled into the alcohol like oil from a sponge.
Acetone May stiffen a specimen. Alcohol may soften a specimen such that it may have to be reset. This depends on the specimen and length and level of submersion.
One may elect to only dip a Lep in alcohol to degrease wings. Or, one may remove the abdomen for a lengthy soaking.
Overall though alcohol has proven far more effective than acetone. It’s also less expensive and relatively safe.
On another note, immediate acetone submersion (upon capture) will help preserve color in odonata, and preserve abdomen shape and color in spiders. Alcohol will not provide these results.
