Well, here's my list of usual items. Maybe I'll round everything up and take a pic:
* Various assortment of flat-head and Phillips screwdrivers including miniature sizes
* Soldering gun
* Needle-nose pliers
* Tweezers
* Small telescoping magnet
* Q-tips / cotton swabs
* Isopropyl alcohol
* Meguiars Plast-X polish
* Endust wipes for electronics
* Orange Glo
* DeOxit
* TDK electronic demagnetizing cassette
* R/C fuel tubing
* Assortment of dental-type picks
* Multimeter
* Test tape
* X-acto knife (or similar)
* 2-inch paint brush
For basic cleaning, just go with a mild detergent and water. For tough stains, grime, grease, and dirt, Orange Glo works wonders!! Just don't use too much of it.
