There is more of a chance some thing will be screwed up by constant cleaning than not. Not very many people wear out a saw. I will bet that I am one of the few that can try to get through a 1000 cords of wood before retiring a saw. The mortality of a saw often depends on many other issues besides how clean it is. A couple of years ago I hid a pretty new saw in a wilderness area and have not been back since. I do not know if there is a chance it is still serviceable or not. I am hoping that I can get back to that area and check it out. I take a new saw with a bar and chain and run it until the chain is worn out then clean it thoroughly put a new chain on and repeat. It has been 10 years since I had a starter rope fray. It has been 20 years since I picked up a saw and ran the saw until the compression became so low it would not power a chain through some wood. I do have spare filters for all my saws and back up saws also. More often a problem arises with the carburetor from some debris arriving through the fuel. Cleaning a saw can cause debris to get trapped into the system. I however do not like dirty saws so when the chain is sharp there will be little to no dust on the saw. Thanks
