Removing grout

Question

I would like to remove the white grout in my kitchen as it always looks brown?!?
I want to replace it with grey grout but am having difficulty removing the old grout.  I am currently just digging it out - i am not very far.  Advice will be much appreciated.

I have used a grinder to remove my bathroom floor grout and my grout in the shower.  You have to be careful or it will scar the grout.  But it is sure a whole lot easier than digging it out.

There are a couple products I am familiar with that allows you to refresh the existing color of your grout or change it to a completely different color altogether. One is called 'Grout Renew' (the company that makes it is Polyblend). The other product is called 'Grout Refresh' (by Mapei). I purchased them both at either Home Depot or Lowes in the tile/grout aisle. Using something like this might be a much easier solution.

Ooops, I just noticed you are in the United Kingdom so you may have difficulty finding these specific products locally. Perhaps you can find something similar locally, or order one of these products via the internet.

the cut off/vibrating tools work well and are easier to handle than grinders for me.

once you get complete; be sure to seal your grout

Depending upon the amount and size of the grout lines there are several products that can be used to do this successfully. 
A multi-tool with a grout removing blade works well. A reciprocating saw with a grout removal blade also works well, They make hand held removal tools that look much like a toothbrush with adjustable thickness blades. These are used a lot for smaller projects or for getting into corners where the power tools cannot reach or work.
A dermal tool (grinder) that looks much like a dentist drill will also work. 
Remember however, this is a dusty endeavor so be sure to close off the area and use a dust mask and a good shop vacuum while grinding to keep the dust at a minimum 
Google grout cutting tools to see all of the types that are available.
