You can try with "carburettor alcohol" - what's it called in english btw =
?

About 80% isoprpyl alcohol, and some detergent is what's inside... And =
it's far cheaper than 100% isopropyl alcohol.=20

Be aware of fire, and vapors from alcohol might not be good for your =
health... and, as well as 100% alcohol, it might be aggressive with some =
plastics....
