I have spoken before of the temperature limited nature of Japanese washing machines. Essentially they only cold wash, which I am sure is a very good thing. That said, I worry about my jeans. I mean they soak up all kinds of filth that simply cannot be dislodged by gentle rinceing in cold water.
Today I boil my jeans.
My biggest pot is a Le Creuset casserole that I have had for decades. It is far too small for the job.
I gently boil my jeans until they are al dente.
I feel I have done a good thing. Must go and buy a big pot for properly boiling jeans and stuff.
