About 25 years ago, while visiting my old grandfather at the nursing home one day, I noticed a near empty can of Water Displacement number 40 next to his bed. Thinking he didn't have a need for that stuff, I asked him about it one day. He said he sprayed it on all his "jernts" each morning and massaged it in. Without it he said he could not get out of bed. I am not recommending anybody use it like he did because it definitely is made for that particular use. But, as most of us know by now, Pledge does not recommend its use for motorcycles either. So, that got me to thinking. If Pap was still alive I wonder if he would have tried Pledge on his old, aching "jernts". I don't know.
