Some methanol was acquired by me after you mentioned it in a different, much older thread. Do you suppose methanol is a good candidate to solve Jan's problem? (Although Sylvia's solution seems best at this point.) Methanol's MSDS concerns me. It makes me reluctant to even open it.
Thank you, 73,
If you're worried about small amounts of methanol vapour, you've obviously led a very sheltered life. My Mum used to get rid of grease spots on clothes using carbon tetrachloride. The lid of the can had a cotton ball for a brush, sort of like rubber cement or oven cleaner.

It gets worse. I can just remember London buses that carried a carbon tetrachloride fire extinguisher in the driver's cab. There is a picture of such a fire extinguisher on the CCl4 WiKi page.

OK. It's high time for me put some methanol into a dropper bottle and put it to good use. It'll be interesting to discover how it stacks up against IPA.
Thank you, 73,
Its a much better solvent for organic gunk but as a smaller polar molecule it has a nasty habit of initiating stress corrosion cracking in any delicate plastic parts it may come into contact with.
Also capable of being absorbed through the skin so don't bathe in it.
IPA is slightly kinder to plastics but very bad for the eyes.
There used to be a contact cleaner thing called Spray-Kleen that, with a small sprit, would make polycarb crumble to dust. It was amazing.
I used some on a part of a Teletype machine and in a second or two all sorts of springs and bits flew out.
It was no doubt super toxic too.
