do not spray anything at all on the sprocket or belt! it gets sticky and then all the dust and small debris sticks on it and works as an abrasive!!!!!! that's kontraproduktiv!!!! keep the belt and sprocket dry and clean it regularly. there is no way of avoiding the noise, except the refurbished super max sprocket or probably the steel one.
The more I read about the sprays, I see that it isn't a good idea to spray anything on the belt.
