Thread: Clean up residual paint

I'm thinking card scraper with a well sharpened edge is the answer.

I'd try paint stripper, working in small areas I found works better. Turps won't really look at it unless it's reasonably fresh paint, acetone will take some off, but it needs to be worked in a small area, otherwise it dries out leaving a tacky mess DAMHIKT.
Being about 100 years old, it would most certainly be a lead based paint, so good ventilation and a mask should be used, even with scraping.
If stripper doesn't work, then I look at Enfields suggestion of a card scraper, make sure you know how to sharpen it correctly.

if the original paint is as old as the molding, or even only half it's age, it's almost certainly tinted with a heavy metal salt -- lead, arsenic, cadmium, mercury, chromium, etc.
None of these salts are people friendly. (in this context a "salt" refers to a metal chemically bound to one or more other elements.)
Besides wearing a good mask -- something much better than the 50 for $14 disposable ones sold by Bunnings -- cleaning up residual dust throughout the building is a must.
