We have taken up the carpets in a house we just bought to reveal the lovely dark floorboards, but what we have (what i guess) is old dried glue around the edges.
The hardened glue is yellow and when you scrape it with something sharp, it scrapes away and it seems to have a powdery consistency, but is hardened like cement.
I have read some stuff online about using vegetable oil to soften it etc but that has had no effect.
I don't want to scrape it off for fear of damaging the wood underneath.
I have also read lots of things warning from using solvents as that could damage the wood also.
So, the upshot is i don't really know the ideal solution here and would love any advice that can be offered!
