The previous owner was always cooking when we came buy to walk through or measure stuff. So when we moved in I realized he always cooked with oil. There was a film over everything! My lights in the kitchen were disgusting. The inside of them should have been white but since all the grease coated it they were now a nasty shade of yellow. I took them down and washed them out. It was so gross! I actually gagged! So when they were all clean and dry I spray painted them black! They look amazing. The lights look brighter with it black too. Weird eh?
