Excellent. Now all I need is a Bunsen burner.

We wiped the crap off the rubber yesterday anyway. If someone knows where else to look where I can easily grab a sample, might you know of someone with an interest in chemistry -- preferably with an assistant named "Beaker," -- who might be able to provide a cheap and cheerful analysis?

The Oregon Dept. of Transportation assures us that their deicer is less-corrosive than NaCl (see http://www.tripcheck.com/Pages/RCMap.asp?mainNav=RoadConditions&staticNav=WinRoadMain , where they say that,

"While [sodium chloride] is an effective tool for melting snow and ice, it also causes severe rust damage to vehicles, degrades the road surface, corrodes bridges, and may harm roadside vegetation."

and

"It is recommended to wash vehicles regularly ... even though the magnesium chloride product contains a corrosion inhibitor, it still can cause corrosion. Regularly wash vehicles to remove anti-icer/deicer liquid, sanding and road dirt encountered during winter months."

Need to find a car wash with belly wash equipment.
