Meths fuel deposits ?

It was meths from an MSR fuel bottle. The bottle has only ever been used for meths. It's designed for petrol fuels only. I was thinking it may be a chemical reaction as the bottle has not been touched for ages.
makes sense since alcohol reacts to cause the aluminium to corrode - must be some of the aluminium is dissolved in the alcohol and produces a deposit after the alcohol is burned off
is it bio ethanol or surgical spirit?, both have additives, or just some contaminated meths. Primus do say that meths will damage their fuel bottles.
MSR bottles are galv. steel but same principle as above. Methanol is weakly acidic and therefore reacts with metals. When used industrially is is considered quite corrosive and special consideration to the materials used are required. It should only be stored in plastic containers for long periods. The other option is your methanol was contaminated with wax?
Looking at it it could well be the bottles interior coating has come away. I only use Trangia bottles with safe pourer to carry meths/methanol.
That's what I thought, at school we have the plastic trangia ones, safer poring for kids.
As rik said. . The fuel bottle may have been a drinking water bottle which sometimes has a plastic type coating inside.
