MP40W cleaning time

I think EcoTech recommends soaking the wet side in a mild vinegar solution overnight every six months or so. I've had mine for just over a year and all I've done is occasionally scrub the wet side components with a brush in left over water change water. About once a month I do that. The propeller cage or housing gets buildup with a few spots of coralline even on the propeller, but a toothbrush takes care of it. Haven't done the vinegar solution soak yet.
