That's for sure!  Even if it doesn't hurt immediately, the residue it 
leaves 
behind attacts more dirt, and in a few months you're back to where you 
started.  That garbage they sell at Radio Schlock isn't any better; I 
bought 
a spray can out of desperation once, and it literally destroyed a pot (it 
dissolved the plastic).

For many years I've used my treasured little bottles of Cramolin Red and 
Blue.  The Red is the cleaner and the Blue the preservative.  They're a 
tad 
pricey but you apply them with a toothpick; for most hobbyists a small 
quantity lasts a substantial fraction of a lifetime.  Cramolin Blue on new 
contacts and such keeps them working like new.  Cramolin Red is what you 
want to clean up grungy card edges and connectors, and those relay 
contacts. 
 This is the good stuff.  (No, I don't work for those guys.)

These products are now made by Caig Laboratories and they've changed the 
names several times over the years.  I think what used to be Cramolin Red 
(cleaner) is now called Deoxit, and Cramolin Blue (preservative) is now 
Deoxit Shield, and they may not even be red and blue any more (sacrilege!).
