I was glad I purchased this. In one evening I was able to restore my 25 year old, hard used, crock sticks sharpener to a almost new condition. They are ready to sharpen 100s more knives and swords to a razors edge. I am very sure that if you used this on new ceramic sticks or stones after every use, they would stay pristine. I have not tried any other surfaces because my ceramics stick were the reason for purchasing.

If you own any Crock stick sharpeners or same style, these are great. I clean the ceramic rods about each 6 months, depends on usage. These will extend the life of your sharpener system, as they remove metal filings from rods themselves. Buying one or two of these is many times lower in cost than replacing new rods, you do the math.

This thing is great at cleaning up my sharpener took a little elbow grease because they were 10 years old but they came back to almost new.

Does a good job. I used it to clean ceramic sharpening stones, and it worked quite well. Also used it to de-rust a knife blade. Again, good job.
