Answer
For stainless grill scratches, sand with the grain using 600, then refine with 800 if needed.
Why it happens
Brushed stainless steel has a directional finish, and mismatched sanding marks stand out.
Recommended grit
Use 600 for light scratches, then 800 if a finer blend is needed.
Wet or dry
Dry first; wet can be used at finer stages with clean water.
Success check
The repaired area follows the original grain direction.
What to do
- Find the direction of the stainless grain.
- Test a small hidden area first.
- Sand with the grain using 600.
- Refine with 800 if needed.
Avoid: Do not sand stainless grill surfaces in circles.
