Ok now for the serious stuff. Most filter oils and fuel contaminations contain Petro chemicals which most have been known to cause cancer and other problems. Children are very reactive to petro chemicals, pesticides and such. I know it seems like a easy fix for cleaning your filter but I would not use the same machine that you wash your dishes in as there are cases of kids getting sick from cross exposure like clothing washing machines. There was a case of a fire fighter that washed some of his dirty work clothes that had residual pesticides on them. They then washed their babys clothes in the same washer not thinking about residual toxins. The warning we recieved stated that the baby died from a reaction to the pesticide that was residual in the washer. Better safe than sorry. IMO.
