I did not took pictures of the next step ...
called as " removing any contamination " (main cabinet) and "removing scratches " from the stand it self ..
I had wash out everything , three times ( hard brash - soft sponge ) ..
And now its drying , for first inspection.
I always do that, if an item that I buy on ebay , was at an unknown environment .
I am a smoker , so I care less about contamination from nicotine ,
but I worry most for all the rest factors.
At industrial environment , even the lubrication oil that is used for some tasks ,
its totally toxic .. oil spots travels from hands to the exterior of some devices ,
the devices travel for repairs , and the oil travels from the device at the hands of the technician,
and he transfers the contamination , at everything he touches = tools like multimeters ..
The Tip of preferring to get on Ebay , shinny clean and in good condition instruments,
its a sign of less or none contamination , from industrial chemicals .
