Syringes in Sweden? Sadly not, you know how it is here. I guess that you might have better
luck in Malmö - at least they have an exchange there! But enough about Swedish politics.
Really, the isopropanol is not too bad. If you just drip it through the atomizer from the battery
end after a good soak in very hot water, it will save your paint and really give it a good clean.
Isopropanol is not particularly toxic (unlike methanol) and any traces left will totally evaporate
if you leave the atomizer overnight. Most importantly, the solvent will dissolve any oily residues
left behind on the atomizer coil from some of the flavours. Water alone just won't have the same
effect. Also, as far as the isopropanol goes, make sure to drip it through the atomizer while
it is still hot from the hot water bath. (Use some tongs to hold it!)
I had a syringe with a blunt needle from an inkjet cartridge refill kit. That's a 30ml one and I
found a 3ml syringe that my ex had left behind from the days when she was studying to be
a nurse. I can honestly imagine that there is nowhere in Sweden to buy syringes, even without
needles, unless you have some magic piece of paper from a doctor.
