Removing grout when tiles had no spacers used

[r_c]

I need to regrout our bathroom, and have never done this before. It does not look like the tiling and grouting was done very well to stat with. There are many places where the grout it missing, and no tile spacers were used.

So .. what is the best way to remove the grout when tile spacers were not used?

I can see a few products out there for removing grout:

• Multi tool like Sonicrafter or Fein
• Virtex grout removal tool
• A plain old hand held grout rake (like this)

Thank you

Dont waste your money on that tool - especially if as it sounds your grout joints are different thicknesses - just use a stanley knife. Hold it at about 45deg to the joint and pull. Then 45deg the other way and pull. Youll have taken the grout out that is touching the tile doing this. Then repeat the above but with the blade now at about 30deg to get the middle of the grout joint. Sounds like a lot of work but its quite quick, and youll do well to damage a ceramic doing this - just make sure you dont slip out the joint and scar the face of the tile (or your knee) and be a little more carefull by the tiles corners.
