A little trick someone passed on to me that seems to work pretty well is to take a Post-It note sheet or similar sheet. Fold it prependicular to the sticky strip so you had a sticky strip on each side of the fold. Run the strips between the keys on your keyboard. It took several sheets for me to clean all the rows on my keyboard. Crumbs, cat hair, etc. down in there.

No EdD there was no B.S. in between the keys.
