I bought an expensive bottle of it from the pharmacy but it near knocked me out when I used it

Chemists charge ten times more than hardware stores, which in turn charge ten times more than the spot price. So from $1 to $10 to $100 as the quantity gets smaller. Chemists will tell you theirs is "medical grade", but that's horse manure. As long as its pure, its all identical.

It won't kill you, but some people are more sensitive than others. If you're one of them, use it outdoors, and wear a mask if necessary. Only uncap the bottle for a second or two to dip a cotton bud and put the cap back on tightly. And of course don't put it anywhere near polystyrene, which will dissolve in it like sugar or salt do in water.

Humm
I used it in the back yard at arms length and it still takes my breath away

so now I keep it at arms length!!

but i can use my nail polish remover and it doesn't really worry me that much which seems ironic

anyways, i have got a $35 bottle going cheap .. ha ha

YEOW! They saw YOU coming! I thought $12 for 100ml was a ripoff.

Sounds like you're one of the sensitive ones. Check out masks at Bunnings. The ones with filters that painters use should work nicely.

And nail polish remover no longer has much, if any, acetone in it. Some people's skin is as sensitive as your lungs, so they reformulated the stuff.

good idea
thanks

the bottle that  I have is a 500 ml bottle

[interest]

I know of what you are going through.
My wife ran off with my best mate, & I miss him.

Nice coins good photos.

hey matty
I have this 1972 fifty cent
and it is smashing
but you can see in the photos the stuff from the PVC holder
do you reckon the (lethal to Robbie) acetone maybe get that off with out ruining the coin?

That IS a really good coin and acetone won't harm it at all.
Worth a crack IMHO :good:

I think it might work.
The dreaded Blue hasn't shown yet!

Acetone is an organic compound. It will dissolve organic things, like the oils in your skin, paints, verdigris, PVC residue. It will not affect metals, or most plastics (though some like polystyrene, will dissolve completely into it).

Whether it will fix PVC damage depends on the damage. In its early stages, yes, it will completely remove the residue and prevent deterioration. Once the acids have attacked the coin however, its too late, and there is absolutely nothing that can be done, other than to perhaps halt further progression.

You've got nothing to lose by trying, and lots to gain. Jut remember to NOT rub, even gently, because you will definitely scratch the coin surface.

and dropping the coins into  the jar isn't too good for them either

then I get the tongs to retrieve the said dropped coin

ermm , acetone and moi - isn't a happy marriage

that 50c seems to have a cloudy surface cover - not patina

I had the 1969 set but sold that - silly me
the coins came from a very reliable source and were guaranteed to be the pick of the day, on the actual minting day

PS Fordie
that 1971 is fantastic!! how beautiful the clear off made it, almost worth the gasping

Just do the process in the backyard on a windy day Mate :ok:

[robbiegal]

got it today
rain and a howling gale

I might also try the sookie la la on the old man
and see if I can con him into demonstrating 'how to handle acetone' as he used to use stuff like that in the bio-chemistry labs years ago

Works up here, "Sweety could you dice the onions,
you do so much better than me, taa::angel:
Yes dear.:dodgy:

Just bung coin/s in a small tupperware container, cover with
the acetone, bung on the lid come back to it in a couple minutes
give the acetone a bit of a swish/agitation. Flip coin over start again.
The acetone does most of the work in the first minute.
Only use a cotton bud if you have too, use it gently.
When finished absorb the used acetone with kitchen paper towel
and dispose. Don't contaminate your original bottle.

[Fulvio]

Don't contaminate your original bottle.

Any HDPE bottle will do for recycling used acetone. Say a clean milk bottle for example. Then next time use that first, top up as required. Just remember this stuff is extremely volatile. Keep containers tightly capped, or it will all evaporate in no time flat.

I've started using LDPE bags and sealing coins and acetone in them for extended baths. That works pretty well.
