Regarding 8-character blind plates
Thread Content
I’d like to ask everyone how to carry out regular inspections and maintenance?
At the very least, it shouldn’t rust, right? Apply butter for maintenance
It’s just a piece of iron plate... Why not protect the part that’s not in use?
Clean the areas that are exposed outside for an extended period; apply rust preventive oil to the carbon steel parts, cover them with plastic film, and remove the film when needed.
