Just got back for the weekend after being away for a month or more and had a look in the boiler of my t500 and there is what looks like mould growing!! Tipped what I had of vinegar in there straight away but not sure how to clean it? Thinking a good vinegar run might work or I have a heap of tow feints stored up but was going to use those for the cleaning run on my bubbler when it's done.
Any suggestions on cleaning the mould? Am going back to work on Sunday so don't have long at home.
