I just moved into an old house that was refurbed with very shoddy work. I am trying to remove what I thought was grout between the tub and tiles and then use silcon caulk instead. I have discovered as I'm trying to remove it that they just slapped some grout over the existing caulk and I am having a VERY hard time getting it out! I'm using caulk removing tools, grout removing tools, a box cutter and a razor scraping device. Any ideas on how I can get this done more easily? This is my first DIY attempt ever! Not going well! Thanks!
