I have a 2018 i3 REx with the pale gray Loft interior which I love. I've managed to keep it pretty clean and bright mostly by not getting it dirty in the first place! But now I'd like to refresh the driver's seat. There are no stains etc, so here's the question: can anyone in the UK with 1st hand experience of this interior recommend a suitable cleaning/refreshing product? Preferably (I think) an aerosol foam or something that doesn't wet the fabric much, and then can be lightly brushed off. Grateful for advice.
