I haven't gone near any of my sensors as yet (and after well over a year with my 400D it is still not showing any evidence of a problem) but for lens cleaning I have a nice big microfibre cloth. Just like the ones you get for cleaning your glasses but it is almost the size of a sheet of A4 paper. Originally it came from the Euro Photo Centre in Uxbridge (now deceased) and I must have had it a good 10 years or so. It is without doubt the most useful cleaning tool I have (and it works well on my spectacles as well).
