White interior - black belt markings

[Sanny]

Anyone else has black markings from using a rear seat belt with a short kid in the seat? Mine is less than a month old and already shows either a worn out white colour or just a black on top of white colour.

Can you provide a pic to help us diagnose the issue? Really close-up if possible.

Tried cleaning with regular wipes - it doesn't go.

Yes, I have the same. Kiddo in booster seat. Baby wipes and leather cleaner did not help.

I haven’t used as I have a black interior. Trevor from M3OC used Gyeon Quartz Q2 Leathershield with good results. They also have two different strengths of leather cleaner:

Q² LeatherShield ceramic leather coating - Gyeon Quartz

Trevor from M3OC install on his X white interior:

You and Dre78 seats look almost the same. I would suggest seeking professional help before experimenting any further. Use the Certified Detailer locator at The IDA to find someone near you. Sorry I couldn't be more help.
