I embarked on an ambitious project to restore a piece of furniture by stripping it, sanding it back, re-staining, and re-varnishing.
The stripping and sanding part has turned into an absolute nightmare. The stain just isn't coming out. Even after hours of work on a single small piece of the furniture, I still cannot remove the stain even near completely.
I just found out that it's largely MDF, not pine like I had thought. Is this why it's so hard to get the stain out? It seems to have penetrated very deeply and isn't sanding away easily at all.
