Help, I didn't seal my sandstone before grouting

    I did not seal my sandstone before I grouted. The sandstone is rainbow (light) and the grout is red quarry. As you can probably guess, the sandstone does not show it's natural colors any longer and has a dark red tint. Is there anyway to fix this? Will sanding help? How about acid? Thanks in advance!
