I find the GT85 spray in the red, black and white cans (sometimes on offer in Aldi) has a lovely, slightly floral smell. Coincidentally, I came across a can of Wurth aerosol lubricant that smelled exactly the same, so I suspect there may be some "badge-engineering" taking place, as the Wurth was over twice the price for a smaller tin.
Just to bring this back on topic, I have dismantled a couple of shredders, and there's very little in the cutter area that could be damaged by lubrication, so spray away!
