Acetone Question

@murrellington: If you look at http://www.homedepot.com/catalog/pd...ik|100141096 it states that the acetone concentration is 100%. I'm no chemist but I'm guess that means you purchased the correct thing. Hopefully someone with some experience will chime in with confirmation.

Klean-Strip is what Home Depot and Lowe's sell. I use it for my coins. It's clear, and never leaves any residue or film, unless the coin is really dirty. It's great for removing glue or nail polish, too.

Thanks guys for the help! Glad I got the right stuff this time.

A simple test is all you need. Take any clean, clear glass dish. Make sure it is clean. Pour a bit of the Acetone on the dish and allow it to evaporate. If there is nothing left, it was OK. If there is any kind of residue left on the plate, it is contaminated.
And for those that have a can laying around for a long time, you should periodically do that test. The reason is that every time you open that can, you allow outside air to get in. As you use some, there is now more room in the can for the outside air. Pending on where you live, the invironment of your home, the amount of air polutions can vary excessively creating a slightly contaminated Acetone.
Also, regardless of what is on the can, remember that the shelf life of that product may be a possible problem. If not a big seller, such a can may have been there for years. No canning process is foolproof and the inside of that can could be slowly disolving into the Acetone.
Nothing to loose by continuously doing the test as noted above.
And as usual, remember that stuff is flamable.

This is where I was going before I realized someone else may have already mentioned it.

Pretty busy store. Glad to hear that the turnover is sufficient enough to keep such products fresh. Not sure if you are in charge of that department or have anything to do with it but one problem I've found in many stores everywhere is the help doesn't rotate the merchandise properly. Hopefully at your place they do but lots of reports of places with outdated products due to no product rotation. With something like Acetone though, a few weeks, months or even a year shouldn't be a problem if old.

Exactly why a clear, clean dish or jar should be used.

Not sure why you would need a soak jar. Usually whatever you need Acetone for works so fast there is little need for a soaking. For coins if you left one in Acetone for 5 minutes or 5 years, would make no difference.
However, if you can find any scientific supply place, they would have regent bottles for sale. All glass for lsb work.
However, I've seen clear glass containers with a glass lid at some dollar stores. Glass jars, bottles, etc. with a glass cover or lid are common.
