Get some 3M or other good quality double sided tape and a bunch of popsicle sticks. You can make your own sanding sticks with any grit of paper you need. They can be carved to a point or any shape needed to get into corners or tight spots.
And you need a variety of tweezers. You may have to file the tips slightly to get them precise...they should be able to pick up the fore-mentioned cat whisker.
