My house has steel bannisters, almost like outside railings along the stairs inside. Painted glossy black.
They seem fine most of the year, but during the hot humid periods, they feel dirty and even lumpy in spots and I realize they havent' been cleaned in 15 years, and I guess normal sweat and dirt from people's hands have been deposited on them.
How would you suggest cleaning them, to get rid of the dirt but not harm the paint and not drip dirty water on the carpet?
Once after I'd been here about 5 years, I thought the paint was peeling off, so I painted part of them, but now I'm pretty sure dirt was coming off and I just pained over the dirt. Still the paint job looked pretty good for years.
