sensor cleaning & isopropyl alcohol

[timmygcsc2308]

ok so I noticed some dust and stuff on my sensor at f/20 so I've got some swabs coming from ebay. But being the dumb*** that I am, I only just clocked that I'll need some cleaning solution too.
I have some 100% isopropyl alcohol that I've used for cleaning CPU contacts, PCBs and other electronical bits..is this safe to use as a solution?

If you're sure that it is clean, then it should be fine. Evaporation difference between methanol, ethanol and isopropanol are insignifcant, considering you only use a one or two drops.
