got a bottle in the shed. Use it for testing for fuel swell. 😀
MEK is basically acetone but with a little extra kick when it comes to dissolving some polymers. Very useful for thinning down silicone and fluorosilicones – look for 2-butanone or butan-2-one on the side of a tube of silicone sealant.
I don’t think it is carcinogenic, not unless you are bathing in the stuff, but due to being so aggressive I wouldn’t be suggesting people use it, or acetone as small splashes will ruin plastic and painted things. If you want a real kick then try THF or DMF 😀 I’m still trying to get to grips with the smell of THF, prefer my old solvent ethyl acetate.
Soapy water (Fenwicks on the bike) for safe bulk removal and then IPA for me if there is anything sticky/oily left. Or if grit isn’t a problem then swarfega is fantastic.
