I hoover the grill once ot twice a month just to keep it clean enough so no overheat would take place.
I also use a lenscleaner disc (the one with several small brushes on it) once in awhile too. but I suspect now that last time I let a person bottow it that it gor little missused. THink the brushes was little messy after that.. so they might just have got the problem worse than it was before using it last time.. it had obiously been laying on some flat surface because the brushes was pointing at several directions so they might been laying in something.. who knows.
but thanks for the advice
this forum is the best I think. atleast when it comes to help from others and knowledge.
well, off to vaccuum the flat and bring the kids to sleep. THen I can start looking at it.
