Dust-Aid is an "adhesive" type pad. It doesn't need any sort of cleaning fluid.
If you touched the pad, remove it from the plastic wand and throw that pad away, then install a new one. No sense risking it.
You should have gotten about 20 pads with the wand. And you can buy more when needed. They are "single use"... Each pad is only good for one cleaning, then should be replaced before the next cleaning (leave it sealed with it's original cover until you need to do another cleaning).
Dust-Aid work fine to remove lightly adhered specks. But it won't remove smears and might not remove more strongly adhered dust particles. For that you might need to do a wet cleaning.
In fact, the first cleaning of any camera should be a wet cleaning, due to oil residues that are nearly always on the sensor from manufacture or thrown off by the mechanisms during initial use.
Go to www.cleaningdigitalcameras.com for more info about cleaning sensors. It ain't rocket science, but there are some tricks to it.
I can't imagine what good wearing gloves would do. To avoid contaminating the tool, just don't touch the cleaning device... in this case the pad which has light adhesive on it, in other cases soft brushes, etc.
