For anyone is interested, I was told by a detailer that you can use a ceramic protector like Gyeon Q2 on your vegan leather.
I plan to do that on my white seats, it basically makes them super hydrophobic and will repel any stains including jean dye. Which really means you can wipe off without any residue staying behind.
I think it’ll pay off over time, we shall see!
Pretty sure they’re already coated with something, and that something works really well! Just take a sponge and pretty much everything wipes off... do t fear your seats!
