Answer
For teak before oil, use 180 then 220. Start with 120 only on weathered or rough areas.
Why it happens
Teak is dense and oily, so sanding dust and uneven scratch patterns can affect the final look.
Recommended grit
Use 180 then 220 before oil. For refinishing weathered teak, start with 120 only where needed.
