I have the sack-up sleeve. When I first started I was wiping with rag instead of water but was afraid I would dull the blade. I went to rinsing very carefully and drying what I thought was well but somehow must have oiled the water before putting in the sleeve.

Thanks for the input, better I got a spot then slamming it on the sink I guess. Knock on wood.

Will change up my strategy a bit using your ideas and stumble on....

How would I get the soap residue off the blade? it was streaking when I used dry cloth.
