Cleaning

 

I’ve found that a mixture of half and half water and glass cleaner such as Windex or Glass Plus will remove tobacco residue and grease very well.  Obtain a selection of brushes to reach into all the corners and a good stack of paper towels.  Apply the cleaning solution as required to remove residue wipe dry with paper towel and then rinse using water instead of the cleaning solution.  Wipe dry with paper towels.  Units requiring substantial amounts of liquid may need to dry for a day or two prior to  applying power.
