Stainless steel cable railing looking a little dingy? Feeney now sells a combination maintenance kit consisting of SteelRenewal for removing stains and corrosion, and SteelProtect for protecting the surface. Marketing VP Andy Penny says that while stainless steel is durable, it can still show stains and suffer corrosion, especially in coastal regions or where airborne contaminants are common. SteelRenewal is a biodegradable gel that cleans the surface without scrubbing. A kit contains one 100-ml bottle each of the cleaner and the surface protector, as well as a brush, a sponge, and a pair of gloves. It retails for $35. Feeney,
