I once in while notice small particles of dust between the keys of my Roland accordion when playing so I’ll take a delicate cloth and gently fit in between the keys in an attempt to clean that area. I’ve thought of buying a computer keyboard compressed air duster in the can and using that with as gentle a blow as I could do but then thought no I may dislodge something doing that. Anyone have any good - safe cleaning methods for that area? I always have a full cover on my Roland when not using it just to prevent this but there’s always a little dust that gets in there somehow.
