Door Seal Mouldy? Machine Smells?

​​Has your washing machine door seal turned black and mouldy?
Does your washing machine smell bad?

The reason for this is a couple of things, first is the consistent low temperatures used by everyone nowadays along with the modern plastic tanks that are used in washing machines.
The bacteria builds up inside the machine and if you use liquid detergents rather than the traditional powder this makes it a whole lot worse because liquid detergents do not have any chlorine bleaching agents in them.
The solution is to use powder and put the machine through a maintenance wash from time to time using the 90 degree wash
