I bought a mostly livable fixer upper. The previous attempt to renovate the bathroom themselves and really made some mistakes I don't know how to fix. They replaced the vanity (already damaged cosmetically) and tiled one wall. There is dried grout everywhere. On the wall, the molding, the vanity (which is grouted in) on the tiles. Idk how to begin getting the grout off these surfaces.

I will probably just replace the molding but what about the wall and the vanity? What about the tile it's self?
