Your Eco Wash Is Doing Almost Everything Right. Here Is the One Thing It Cannot Do.
Washing cool saves money and is kinder to your clothes. It also leaves something behind that a cool cycle was never going to shift.
At some point in the last few years most of us quietly moved to 30°. The energy bill, the care labels, a general sense that boiling your clothes is not really necessary. It was the right call and I am not going to tell you to stop.
But it has a side effect that nobody mentions, and it took me about four years to notice it.
Detergent needs heat to disappear
Detergent is designed to dissolve, and how completely it dissolves depends a great deal on how warm the water is. At 30° it dissolves less completely than it does at 60°. A little more of it stays behind in the machine at the end of the cycle instead of leaving with everything else.
Once, that is nothing. Three washes a week for four years, and it is a film.
Which is why the smell arrives so slowly
That is the part that makes it hard to catch. Nothing changes overnight. A machine gradually stops smelling of nothing, and because it happens across months you stop registering it, the way you stop hearing a fridge.
Then one day something comes out of a finished wash and smells faintly sour twenty minutes after you put it on. And you blame the detergent, because what else would you blame.
Go and pull your door seal back with a finger before you read on — it takes two seconds and you will know immediately whether this is you. If it is, this is what I use.

Your manual probably already tells you this
Most washing machine manuals recommend a maintenance wash — an empty cycle, run hot, every month or so. Go and look at yours. It is usually a short paragraph near the back that nobody has ever read, and it exists precisely because a normal cycle is not designed to clean the machine itself.
An empty hot cycle on its own is just water
You can run one with nothing in it and it will help a bit. But water is water. It is not especially good at lifting a greasy film, which is exactly why you put detergent in with your laundry instead of just running a hot rinse.
A cleaning tablet is that same idea pointed at the machine rather than the clothes. Drop one into the empty drum, run it hot, and go and do something else for an hour and a half. It dissolves slowly across the whole cycle, so it is working through the drum, the pipework and the parts you could never reach with a cloth.
Once a week after that, on an empty machine. If yours has a few years on it, use two or three on the first cycle — you are clearing a backlog rather than maintaining one.
Keep washing at 30. Clean the machine separately.
One tablet a week, 12 to a box. Right now the second box is free — about six months in total.

And please do not start washing everything at 60° on my account. That is not the fix and it costs you the thing you switched to 30° for in the first place. The point is that you can carry on washing cool. You just have to clean the machine separately, because the cool cycle was never going to do it for you.
