I got this small hand held blower for cleaning my projector and PC, I do use another attachment which I have that is a very small tube for getting right in there, (Oooo er Misses, 'ave you ever got right in there), any-ways it's good for the job and @ £11.99 you cant go wrong, saves on those dust aerosol cans which if you point in certain directions the liquid comes out into the unit.
