- Does not scratch (microfiber is therefore unsuitable)
- Not fluff
This cloth fulfills both criteria. It is very soft, and it fluff virtually not at all. Therefore suitable for all sensitive surfaces - not only blades but also piano lacquer and the like.
Washed I have not yet, so I can not comment on whether the quality declines thereby. According to Care label, it is washable and can be tumble dried at up to 60 degrees, which also suggests a high level of quality.
