Decided to vax the mats and boot floor... thing.
Then treated with Gtechnic smart fabric.
Will vax the seats once the warmer weather comes, but leave the Smart fabric for the mats only as without kids or pets I think we can avoid spilling onto the seats (famous last words)
The previous owner service the car as per spec but probably weren't into cleaning it, so after wheels and calipers sealed then car detox wash, fallout remover, tar remover, clay, DA polish and wax, Sonax hybrid seal the mat trim.
Always nice to start ownership with a clean car.
But I fear its a slippery slope.
