When using acetone, set up your work area near an open window/door, then place a fan so that it blows across the surface area away from you but towards the open window/door.

I use this method in the kitchen for dealing with chopping onions as well.  It works very well. :angel:

oh ta

I have used a little pickle jar
so it is deep and glass
then my silicon tipped baby kitchen tongs

I have stacks of Tupperware ...

ps - do you guys reckon an ultrasonic might also work?
I have a small industrial one, my daughter gave it to me as she is a rep who sells them to hospitals

I wouldn't try neat acetone in an ultrasonic cleaner. That would be a good way to generate lots of fumes.
I have tried an ultrasonic using water and a dash of acetone for sticky residues (tar, chewing gum. plasticine or such resembling) and it seems to work well. My little ultrasonic goes for 30 minutes per button press and usually needs two or three hits to remove stubborn gunk -if it hasn't removed it (or softened it) by then it probably never will. Remember that most US cleaners recommend 50 duty cycle; ½ hour on then ½ off.

I sit the coin(s) on a piece of polycarbonate sheet cut to fit the base of the cleaner to prevent metal to metal contact. The basket that came with the cleaner is metal mesh but some have plastic baskets.

Jeff, where did you buy your ultrasonic cleaner?

[robbiegal]

thanks jeff
nah - i'd never use the acetone in the machine so that is all good
never knew you could
I am sure that miss daughter would ban me from doing that to the machine

I did cut up some silicone (from a baking silicone tray)and line the basket with that

the daughter said that with the ultrasonic you do the wash in the machine then clean as you would, so I imagine you could acetone before or after

anyways, I might try it as the coin may look better and last longer as well
if not, I will have done my $110

Lighthouse sells one with a plastic basket for coins.!!

[robbiegal]

cool
that sort of looks like mine

but the one I have sells for well over a thousand dollars, hospital grade for instruments
it was a loan item and then it got loaned to me .... permanently IYKWIM

I am not entirely convinced that they perform any great miracles
i'll see if it razzes up my 50c

It will work but at the end of its cycle you will have
a nice shiny Cleaned coin.
Defeats purpose of attempting restoration.
Wouldn't use it myself.

[robbiegal]

oh

ta

and ta again (*puts ultrasonic back into the cupboard)

so in a nutshell, it will stuff up my coin
it is a special coin to me
so i'll avoid doing that to the little lady

[JeffH]

Jeff, where did you buy your ultrasonic cleaner?

As I recall it came from Jaycar. I never bought it for coins though -cleaning carburettor parts and such like it does a great job.

A quick Google and eBay search turns up literally hundreds of places that sell them.

[robbiegal]

I can get you one  $1,500 !!!
maybe a little less!!

Thanks Jeff ....... I did notice the car workshop manuals on the bookshelf near the old key rack!!! HQ-HZ ....... I've got two WB's out the front (202 & 253) ..... it's a race between me and mother nature as to who gets to do their resto!!!!

[robbiegal]

they are worth a small fortune these days aren't they?

Pretty popular for the B&S youngins and ute musters etc. A fair few tradies like them too. Not sure what the current market's like, but they were pretty sought after a couple of years back.
