Clean Duplo stones
Every two years, it is time to remove the sticky dust from DUPLO bricks (as well as LEGO).
Namely, I throw all in a pillowcase - better still together with the pillow (otherwise it will be incredibly loud in the house) and let them through half an hour in the normal wash.
Alone the shower is not enough, because you do not come in the interstices and with small children in the house, but sometimes sticks one or the other obstrest in it.
Much relief.
