When we replace said chairs, I want to bring those home, but this time we carried a club chair home (we might be the only family who takes old things from the beach property to the home property).
So I bought a couple of bottles of Tilex to give them a good cleaning. There is no place on the property there to get after something with a water hose, so I used pails of water to rinse the chairs down when I was done.
On one trip to the balcony I slipped in a spill of water and fell flat of my back and knocked my head against the tile floor. No breaks or splits, but I feel every one of my years and then some days later.
But the old chairs look pretty good.
