Thanks, I’ll look into Rael. I thought about doing it myself but when I looked at what’s involved there are some chemicals (a cleaner and a brightner) that require thorough rinsing and I am worried about the runoff getting into the pond if rinsed down the gutter, or hurting the lawn if I do it in the grass. I had a neighbor chew me out for washing my car in the driveway. If they just needed a little touching up with some oil or sealer it woulf be different, but we let them go too long.
