How to dry after black oxidising?
Dry the parts with a clean, lint-free cloth immediately after black oxidising, otherwise corrosion may form.
Regarding the waiting time after black oxidising: It is important that the black oxide is completely finished and the surface is dry before you start painting. As a rule, a short waiting time of around 30 minutes to 1 hour is sufficient to ensure that the surface is stable. If the humidity is high, it may be advisable to wait a little longer or carefully heat the parts to speed up the drying process.
