Any tips / best way to remove grout for renewal?

ferry

Just need to do a bit of a tidy up job in the bathroom and will look to removing as much grout out as possible for a re grout. Tried the little hand tool with the carbon blade but found that useless

Any ideas on an alternative way for this job appreciated!

Multitool with a carbide blade. But if you have very thin grout lines, you may find a carbide blade too big. In which case, a Dremel with a diamond cutting disk might be your only option.

There are diamond (grit) multitool blades - 2mm and ridiculously expensive at SF, but almost certainly cheaper somewhere else.

With some skills it can be an angle grinder with a thin disk. The smallest I see at SF is 1mm (76 mm diameter)

There are even smaller discs and very small angle grinders.

I've used one of these in the past which worked reasonably well - (much quicker than the hand tool you tried - I always end up blistering the palm of my hand with those) You'll probably break a few of the bits though and obviously you'll need to buy the Dremel if you don't already have one

I used an angle grinder with metal cutting disc to remove the grout around some tiles to remove and replace them. Worked really well

I did this in a previous house. I got a dremel multitool and picked up the grout removal kit. Worked a treat. It can create a hell of a lot of dust mind. I have one of those industrial wet/dry vacs from screwfix, so used that for dust extraction.
