You might be able to grind it off carefully using a dremel tool.
I've used a tool called a grout saw to remove old grout. It was just like this one that has replaceable blades: https://www.amazon.com/ToolUSA-8-Inch-Angled-Grout-Saw/dp/B00VUGRPWE/ref=sr_1_1?keywords=8-Inch+Angled+Grout+Saw&qid=1548089379&s=Home+Improvement&sr=1-1-catcorr
Keep in mind, the blade is too thick for really thin grout lines and older grout is harder to remove than recently applied grout. It's a tedious job but it's worth it.
