My mom's kitchen has white ceramic tiles and beige sanded grout. The
beige becomes brown quickly due to food spills and whatever. Last time
we cleaned it, I applied a sealant. A few months later, it's brown
again. What is the best way to keep it less stainable? can I put epoxy
grout on top of the sanded grout? or a grout "paint" that seems to be
used for bathroom wall tiles? thanks

Sanded grout has a rough surface which easily traps dirt.

What kind of sealer did you use? A penetrating sealer or a surface sealer?
How many coats did you use? A different kind sealer or more coats of the
original might help. If you used a surface sealer, you will have to strip
it before using a penetrating one but you can apply a matt finish acrylic
surface sealer ofen grout with a penetrating sealer already in it.

I suspect you used a penetrating sealer for a natural look which leaves the
grout just as rough and likely to trap dirt (though it may be absorbed
less). A matt finish surface sealer should be more acceptable to you as it
will smooth and seal the grout surface. You may need to reapply in a year
or two though depending on traffic.

You would need to remove the grout to replace it, another layer on top
(epoxy or not) would likely flake off in short order. Epoxy paint I think
would look worse unless you painted the whole floor monochrome.
