peejay4A Posted January 2, 2020 Report Share Posted January 2, 2020 By way of clarification, meths or methylated spirit is not methanol. It’s mostly ethanol with some poisonous additives and colourants to make it unpalatable to drink. Quote Link to post Share on other sites

john.r.davies Posted January 2, 2020 Report Share Posted January 2, 2020 As a student on a Denmark secondment, o stayed in student flats with engineering and chemistry colleagues. They bought the adulterated ethanol sold by pharmacies, and removed the bitter stuff by column chromatography! John Quote Link to post Share on other sites

peejay4A Posted January 2, 2020 Report Share Posted January 2, 2020 Paraffin is cheaper for large objects. Brake cleaner is an alternative. I use IPA for more delicate work. If your supplier was giving you >5% methanol you were done Pete. Quote Link to post Share on other sites
RobH Posted January 2, 2020 Report Share Posted January 2, 2020 This thread was discussing cleaning out a clutch hydraulic system and the subject drift is now liable to cause confusion. Surely you are not advocating the use of paraffin for that are you Pete? Quote Link to post Share on other sites
