Gliptone is good, Leahter Masters is good, Leatherique is good but it isn't the best for regular maintenance. Most of our leather is already"damaged", the clear coat is failing, there are visible cracks etc, and the best that these products can do is to prevent the leather from getting worse.
Meguiar's Gold Class is no good, and your average OTC Lexol isn't very good either. Chemical Guys conditioner is okay but not at all durable.
Clean leatherette with 303 Fabric+Vinyl cleaner and dress with diluted 303 Aerospace protectant, Sonax Matte Dash cleaner or another vinyl protectant that wont wear away quickly.
