What is the best type of wool?

Inox Wool: It is more agressive than the Brass wool and so will require more care when being used. It is the most effective when used less aggressively and therefore minimizing the abrasions – Remember! Less Is Better. As well as being more effective, Inox is much more durable than Brass. It is more flexible, less fragile, and as a result, reduces the amount of particles and contamination of the work area. In tests we found it very resistant to breakage and it contained less than 10 times the amount of broken particles than in Brass wool.
