Methanol Question: Can I use another type of alcohol to disinfect the filtration apparatus?
The simple answer is no. Methanol is the only alcohol that produces formaldehyde gas as a by-product of combustion in a low oxygen atmosphere. Neither ethanol nor methylated spirit can be used to give the same result. If you do not have a supply of methanol, please refer to the question about alternative disinfection strategies for advice on how to proceed.
