Igniters keep clicking on gas burners - Dacor Preference SGM365SS Gas Cooktop

I did have the same problem after the house keeping people done with cleaning. They used window/surface cleaner. First I asked them not to clean the ignitor with any cleaner. Here is what I did to solve the problem
I took scotch scour pad (one that you use for washing dishes), In dry state I polished ignitor switch. It is abrading the residuals and deposits on the top and polishing it. Don't use any thing more abrasive than that. MAGIC - I don't have any more problem.
