I've got one of these wands with the foam pad at the end.

I accidentally touched the foam pad with my finger before putting it on the cleaning strip - there is apparently a risk that oil from my fingertip got on the pad.

Is this a real risk? Should I not use it?

Thanks

It's not a risk, it's a certainty. You have probably also transferred some microscopic grit to it.
Please don't use the pad - they are relatively inexpensive. Make sure you use the correct solvent (Eclipse or similar) for your sensor. Here's a link (external link)


Several cameras and more glass than I will admit to.

Do you mean specifically solvent rather than a pad/sticker thing?

I am pretty sure the one you have linked is a "dry cleaner" and does not use any fluid.

Yeah it is, I was wondering what noisejammer's recommendation was - his link is to a few different products

Would it have be a good idea to wear non-powdered nitrile gloves when doing a job like this? -rick

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.cleaningdigitalcam​eras.com (external link) 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.

Copperhill states "If you are totally new to this procedure, you might consider powder-free latex gloves, at least in the beginning." I am not sure why they suggest latex gloves as opposed to nitrile except that natural latex will not develop a static charge as readily as nitrile. But the difference is very slight and of course some people are allergic to latex. People that work in electronics commonly use this technique to reduce static charge and antistatic gloves are available in both formulations (as well as others).

I got a new wand which came with a pad on it.

As far as I can see in the instructions the pad is reuseable - you just use the stickers to clean the pad in between uses.....
