Fix a squeaky swing at playground

Many children are highly sensitive to noise and squeaky sound and my son is one of them. Due to lack of maintenance, the swing at playground which nearby my house started to make squeaky sound. When it comes to fixing a squeaky swing, WD-40 can be quite handy. All we need to do is just spray WD-40 lubricant over the body of the chain and connective clasps. Make sure to cover all areas where metal pieces meet. This lubrication and cleaning will ensure that the squeaking stops.
