We're going for quite a modern look in our new flat although it's almost 100 years old. It still has the original stairs which underneath the many of layers of paint seems to be in good condition. I'm just wandering what's the best way to get rid of the many layers of paint. What product(s) do I use? I don't want to damage the recently skimmed walls and I have a toddler so I don't want to use anything toxic.
