guys.. guys.. guys.. just relax.. you can get a replacement panel in the market starting from 50 bucks and going around 400 for the original.. why make a big fuss about it.. just save your original panel.. use any of the panel you buy (it would come in handy if you are going to resell your mob..
Then for the cleaning it is a better to use only soft paint brush.. DO NOT USE ANY LIQUID.. some dirt can be just blown off using a handy vacuum cleaner..
