Leather ventilated seats

[Whites]

Is there any recommendations regrading cleaning and protecting / nourishing  the seats 

[Zotto]

Lexus manual suggests cleaning with water and neutral whool  detergent. Many people I know use products  like cream for hands care or even milk (!) to soften leather.

I use Gliptone leather cleaner first - dries quickly without clogging the seats - followed by Gliptone leather conditioner - this is easy to work with, smells nice and leaves leather soft and supple with no greasiness

Just use the solution recommended in the owner's handbook, or the leather cleaning kit Lexus supply. It's not difficult...
