Query: Clogs, mold grows inside

I thought I liked this mister. I could deal with the clogging, just rinse it out and it seemed to work ok again. I clean it about twice a month by completely emptying it of oil and washing with with dish soap. Today, I looked inside and saw dark blotches on the outside of the plastic inner bottle, but inside the stainless exterior. I used a small flashlight to get a better view, and I was shocked to see that it was clumps of mold. It is impossible to take it apart to get it out of there. It makes me sick to think I could have been spraying my family's food with contaminated oil, and who knows how long!
