Years ago we purchased the black cast aluminum furniture called “Chandler” patio furniture from JCPenny. (you can still see it on their website by looking up the word Chandler). The problem has been that if you touch it, it colors everything black, like a very inky newspaper. We’ve tried to wash it twice a month and wax it with auto wax at the beginning and end of every season like most websites say, but have never been able to correct this problem. We’ve had more than one person tell us that if we seal it with a spray sealant, it will just chip off and take bits of the powdered coating off with it. We love the furniture otherwise, but would like to know how best to take care of it. We would appreciate any genuine advice that correctly addresses this problem. Thank you!
