About 10 years ago, I actually used dSLR sensor swabs more than anything else. In those days, the swabs were fairly cheap, and I had to buy them for my work cameras already. That's before self-cleaning sensors tech existed on pro dSLRS as it does now (and for at least 5 years).
I have some of these: http://amzn.to/2Gvx1hW
That exact item is no longer available, but with the photo shown you can probably find something similar.
I see many here: https://www.amazon.com/s/ref=as_li_s...3b3041ba2a0906
It just needs to be non-fabric/cotton/etc,
Paper is also a terrible idea. Paper is made from trees. Would you rub tree bark all over the VCR heads? I'd hope not!
