removing ink from vachetta

Ink on the "suede"--are you speaking of the interior suede-like fabric (alcantara, I think)? If it's fountain pen ink, try Amodex. If it's ballpoint-type ink, try blotting (not scrubbing) with rubbing alcohol.

speaking of rubbing alcohol.......
iv used it before on a white leather...the ink is gone...
but after sometime the area turned into light-greenish color...
 
^^Thank you, I did find this but its already set it.

6.For ink stains and other dirt, use a white eraser and erase the spot (do not use too much pressure - and check to see if the color is coming off). Usually if you get the ink right away you can remove all of it. Ink migrates into the leather fibers so once it is set, you need professional care.
