I've had mine with Wheat interior for 3 months. Like any lighter colour interior, it is harder to keep clean, but I've found that stains wipe off quite readily. I've had blood, ink, oil and normal dirt ... all of which came off easily.

I agree with DalRock that the floor mats do get dirty quickly. However, they've also been very good with respect to cleanup. So far, no stains have really set on the floor mats.

Does anyone know if Scotchguard has been applied to the interior carpeting of the EX from the factory?
