I have wiped and cleaned my hose a few times, But have never to be honest cleaned out my Slx. I was getting a bit concerned of wear due to seeing scratches Etc.
I have just spent twenty minutes with a friend helping, properly cleaning all sections and all the hose. Thing looks almost new again. It was a bit tight sometimes opening too, Now is smooth as anything. Any sort of wax or anything to put on it ??
So I suppose the answer is, Don't moan about things wearing down, Look after them in the first place.
