I still use Einszett Cockpit Premium, which I get from Waynestowels.com. I use Lexol Leather Cleaner and Lexol Leather Conditioner on my leather, but I have never tried it on the dash and the rest of the interior (that's what I use the Cockpit Premium for).
A lot of people like using the 303 Aerospace Protectant on their interior because it lasts long. No idea how it makes the interior look or how it cleans or anything...it's just supposed to protect for a while.
M Speed, you should checkout autobarn.net, properautocare.com, or autogeek.net to make orders for more Lexol. Shipping sucks so I usually order a couple bottles of each product, each time.
