So are all crop sensors the same size, i was under the impression they were different sizes, thank you for your reply Mike

All the Canon APS-C sensors are nominally the same size (1.6×crop), and are slightly smaller than those found on Nikon/Pentax/Sony Aps-C sensors (1.5× crop). I have seen swabs specifically for both the Canon and the other sizes, but the difference is I think under 1mm in nominal size, so it's not really significant. The different sensors in various models of cameras from the same manufacturer do again vary slightly in size, but generally I think that is usually in the region of 1/10ths of a mm. An APS-C sized swab should work perfectly fine.
