A small piece of 'microfiber' toweling would work even better as it will 
allow the abrasives to embed in the fibers where a few strokes to help 
dissolve the contaminants will not cause harm.  Ones fingers can be 
surprisingly abrasive.

Then rinse well to remove the soap film, with a final rinse in distilled 
water.  Let dry _well_ in a < 40% humidity environment as damp magnetic 
coatings are VERY abrasive.  The least abrasive is cold, below 50F, and low 
humidity as in less than 50%.  I have seen some curves that show feeding 
videotape through a vcr at 80F and 80% RH causes 20x the wear that cold dry 
tape causes.

Cheers, Gene
