Gliptone order arrives tiomorrow
I use engine degreaser and water on a 1:5 ratio.
Keeps it looking factory fresh and completely matte.
All you are doing is getting the grease etc. off the top coat, that is the stuff that shines.
You get your gliptone yet , still waiting on mine.
It will remove the shine until you sit in it again.
What the degreaser?
It will keep it looking matte for another year or two, as long as you give it an occasional wipe down with a dam cloth.
I am not a huge fan of the Liquid Leather myself, I don't mind the cleaner, it works quite well, but find it keeps looking matte longer if you don't use the conditioner.
I do like Furniture Clinics cleaners.
Their alcohol cleaner is amazing, but to be used sparingly and only once or twice at most, and their Ultra Clean is great for regular updates.
