The metal body of your Dovpo Riva is zinc alloy.
I would try using use the
same technique that's used for auto finishes.
1) obtain a couple high-quality microfiber 200 gsm - 400 gsm towels
2) properly clean your mod (as outlined below) using circular motions
3) check to see if the scratches are gone
4) repeat the cleaning as needed
Most microfiber wash mitts and towels today are soft enough to provide scratch-free washing and drying performance, but it’s still a good idea to doublecheck the weight of the material, just to be sure. Microfiber towels should be at least 200 grams per square meter (gsm,) with the best-quality, professional grade towels weighing in around 400 gsm.
Selecting the right car wash soap is also critical to helping you avoid scratches while cleaning your car. Avoid dish liquids altogether. Instead, choose a high-performance car wash soap with plenty of lubricating agents and foaming action. The foam will help surround any loose soil particles, forming a protective barrier between the dirt and your paint, and the lubricating agents will help you wipe and rinse away that dirt with minimal scratching.
FWIW, folks use microfiber cloths on the clear coat on automobiles to remove surface scratches. Microfiber towels do not remove any of the clear coat or paint.
Good luck!!!
