I am in the midst of renovating the cast iron railings on the balcony of my 1860s built property and was interested to know if anyone else had successfully attempted this. If so, what were the most efficient ways you found of removing layers of old paint? So far, I have used paint stripper/wire brush, an angle grinder for flat surfaces and Dremel with grinding point for the detailed sections but there is still a lot of work to do!
