A good trick is to get some of this
Make a bit of a slurry and use a toothbrush to really clean in the grooves on the grip. Especially if you don't use a traditional tacky wrap grip. Tour Velvet, they have those little notches that can really hold dirt. It might take a while, but its worth doing every month or so, instead of tearing off grips when they are still perfectly good.
Or I am sure @iacas plug these guy http://www.puregrips.com/, and give you a good testimonial on how durable those grips are
