Don't excuse yourself for an opinion Kevin, when it's based on facts. ;-)
It seems necessary to repeat this pot-cleaning message once in a 
while, even though it should be common knowledge by now. Many still 
consider Radio Shack spray cans as the magic solution, just like the 
manufacturer wants us all to believe.
I've been spending half my life preaching that spraying (of any kind) 
will not do any good. It's the only available quick-cure when a pot 
suddenly develops a problem on stage or in the studio, and the 
recommended thing to use in a situation like that, but replacing the 
pot should be the next thing shortly after that.
Better safe than sorry.
