Today when we were at the park and Joshua wanted to sit in his favorite blue swing, I remembered that the swing squeaks and makes such a terrible noise. I asked Hector to go get some WD-40 and sure enough it worked. The swing is ultra silent. Yesss. So that Hector and I talking about the many uses of WD-40 and here are just some of them . I don't think I'll be using it for everything but it does sound handy.
