I actually think the gloss piano trim is very scratch resistant although can be quite a dust magnet. I've had my car 2 years and there's on,y a tiny scratch on the gloss trim. Much more robust than I thought it would be.
If you are interested in keeping it clean, whilst protecting it from scratching, the key is little and often cleaning and gently does it. Use a decent anti-static trim cleaner/dressing. I use Poorboys Natural Look Dressing. Or as suggested try a decent glass cleaner, which works well on the infotainment screen too.. The one suggested by CHB is the best glass cleaner I've tried, it's unbelievably easy to buff off with the merest of pressure, and if you use code VWROC10 at checkout you'll get 10% discount. The other key item is a very soft Microfibre. DoDo Juice Fantastic Fur microfibres are brilliant for final buffing, or WoWo Microfibres are perfect for a variety of jobs and a nice light fabric weight for interior work. GTIFORUM20 will get you 20% discount on WoWo gear. And for touchless dusting a can of compressed air (air duster) is always handy to have around.
I don't wear rings.
