It really bugs me when my instruments get marred..I take extra care to prevent damage to my equipment..That is why most of my stuff is like new..I don't even like the bottom of my keyboards scuffed..

Always carry your keyboard in a quality case..Always use quality keyboard stands with rubber scuff protection...and the "BIGGY", always handle your equipment...no roadies..

I always clean the surfaces and never leave finger prints on my boards..After my job[gig] ..I make sure all the film and room dust are removed...It may seem overkill , but it works for me..
