Can I also ask how you dry your Matt car? I use a fibre cloth but the dealer says a shammy is fine?
Car washing has moved on significantly from the single bucket, sponge and wash leather days, and I wouldn’t use a wash leather - or a sponge - on a car whatever the paint type, even if the dealer says it’s fine to do so. I don’t think any of the dedicated detailing websites would say it’s fine to use a wash leather for drying either; they’ll be recommending plush microfibre drying towels.
Most dealers have probably never heard of the safe two bucket (or three bucket) wash method, let alone use it. Most dealers would say a bucket, sponge and wash leather were fine to use on any car paint type - that’s what they use for complementary services washes - and the water used is often what’s left over in the bucket from the previous car, so could be dirty and full of grit
. That’s why I don’t ever let the dealer wash my car.
i don’t have matte paintwork but I use similar products to
@EdwinV, and like
@EdwinV, my car cleaning kit (lambs wool wash mitt, drying towels, wheel woolies) also gets washed after every use. I would feel happy using the same kit on matte paintwork, but would change my existing shampoo / snow foam to products that are specifically for matte paintwork.
For drying, I use a warm air dryer to remove most of the final rinse water from my car (it’s also very good at removing water from those annoying water traps that most cars seem to have - grilles, along window rubbers, around door handles, badges, door mirror housings etc.); any remaining water droplets get mopped up with plush, double thickness microfibre car drying towels.
