Purchased vehicle in May 2020, this problem was first noticed around August 2020.

I have a blue minivan with light gray seats. They stain when you spill water on them. They stain when you think about spilling water on them. They stain under the water proof car seat covers even though you never spilled on them. Some of the stains come up with frequent carpet cleaning and industrial chemicals. But I mean, I drive a minivan. I have kids. They are messy. I don't have time to constantly clean the seats.
