I need to re-grout a bathroom ceramic tile floor with badly discolored
grout. The grout line width is 1/4 inch. What is the easiest (and best)
way to remove at least 1/16 - 1/8 depth of the old grout? Is there a
power
tool that won't damage the tile?

Thanks, in advance, for your help!

Grout isn't really that hard. You should be able to rake it out with the
proper hand tool. They make one for this specific purpose. A power tool
will make a lot of dust.
