>>> Thank you! I thought I read somewhe to start with hydration process 1st if leather is dry...
That is very right (do you know the reason?).
>>> Ok so next step is degreaser, acidifier, hydrate then back to hydrate system 1 more time correct?
Correct!
>>> I didnt use eraser yet. Recommended?
Eraser-4 is used in conjunction with the leather Brush-1 - so as to brush and scrub of surface contamination during the wet cleaning. Eraser-4 is also used after the leather is dry so that wick up soiling is again erased away. Depending how deep the penetrated soiling is coming through - dry erasing is a time for inspection. If you are not too happy with the cleaning. You may start all over again in the recommended sequence.
The kit you used is Kit-V7 - Louis Vuitton Vachetta Leather Care Kit

And you should clean the logo panel first, before you start cleaning the Vachetta trim (practical reason you can experience it yourself if you do the other way round).
