Stan,
I use a commercial solution, Chem-Crest 235, that I reduce to a very diluted form. It has no abrasives in it, I have not used spic and span. I would think you are correct in that any abrasives would wear on case colors. I have been amazed many times by putting something in the tank that looked brown or just covered in patina and once removed the engraving is sharper and some colors actually appear.

It works amazingly well and is the least intrusive method of cleaning I have encountered. You do have to be careful to blow off the excess fluid and oil immediately after removal from the tank or the metal is prone to rust. I have also heard of some damage from people using the wrong solutions. Great tool for the gunshop and one I would never be without.
