Since you have a deck just purchase a tent to put on it.  This way you could go out there in the Winter and do anything you want.  And too, no one could see you with your coins. Actually if you do use a bit of Acetone and use it on one coin at a time, anyone that does see you wouldn't have any idea your a coin collector. |

The main reason I'd take one out at a time is if I trip or drop it, I'm only chasing one coin, but yeah, this way I'm not sitting out there with a whole bunch of coins.

Acetone, like any high volatile hydrocarbon has explosive potential in a confined space.
As little as a tablespoon in a 200 liter drum is enough to kill.
This video is more about welding and drum safety, but acetone was the culprit in this case:

Thanks for the warning! Outdoors definitely seems like the way to go. Also, given the flammable nature of acetone, I think I'll put the table on the far side of the door, away from the outlet, even tho it's capped. It will be slightly more visible from some angles there (esp the ladies next door), but I still think it won't be that obvious what I'm about.
I was thinking a few minutes in the bath ought to be good enough, but I just saw another thread where someone left the coins for over a day. These coins are not particularly dirty (most have been cleaned, as I say), so this is just to remove any PVC residue. How long do you recommend?

Also, these coins are different metals, and I gather you should change out the acetone between the types, right? I gather the best disposal is simply to use as little as possible and let it evaporate after? Can you rinse the dish in the sink once that's done, and is it safe to put it back in service as a teacup or dessert dish, or is it forever afterwards a dedicated item?
Sorry if these are dumb questions, but better safe than sorry!

I use a small glass and I put it through the dishwasher afterwards. acetone rinses out fine. if I remember correctly it is also a natural by product of fermentation so a little bit is in every beer.

Acetone won't be quite as effective cold as at room temperature, but either way a 5 minute soak ought to be enough if your coins aren't covered in tough goo. On circulated coins, I sometimes use a natural bristle soft swab brush to help with cleaning without danger of abrasion.

20s is enough to remove phthalate residue. Careful not to get anything like 2% in air as that is the lower explosion limit. Use it in a ventillated area. And do not keep repeatedly dipping and air drying as the coin will get cold as the drying loses the heat of vaporization. Then it will rapidly collect moisture from the air.
