Hi, some of the grouting around the top of my bath and between some of the tiles has been steadily going brown/black and won't come off when scrubbed anymore.
I want to re-grout, but understand that I need to remove the discoloured grouting first.
Can you tell me how to remove it please?

Its not easy to remove it.
Have you tried washing it with bleach diluted?
If you do want to remove you need to scrape it out, you can buy a tool, be careful or you may chip the tiles. When you re grout use the correct grout.

all grout will discolour eventually, as said ,bleach is brilliant at cleaning, wear gloves etc. use a small brush - old toothbrush I use.
grouting is a messy job too but worth doing every ten years or so with waterproof grout, dig out old with a grout cutter only .

Mix bleach and bicarb of soda into a paste put it on the grout and leave it for a while to work, then wash it off. Good quality bleach is better
