Re: ATM Silicone Oil

["Raymond W." <fire.mountain@post1.com>]

Silicone oil is very difficult to remove, if not impossible. I worked with
an engineer years ago who recounted a story of how (for whatever reason)
put a little such oil on his bathroom mirror. When it steamed up after ahot
shower that spot didn't collect condensation. It remained this way for
years and years, despite weekly cleaning with the usual commercial glass
cleaners. (There was a suggestion of using such oil to write "I'm outside
waiting for you." on the bathroom mirror in a hotel, giving guests quite a
surprise, for years -- if management heard complaints repeatedly they'd be
sure that the room was haunted.)

My Windows-84 computer (a Mac) notes that Clive sent this circa 12.07.98 :

|   On the subject of putting fluids on your mirror  surface, let me
|recount  a horror story that happened  to a friend's 20"
|mirror............. .... It would appear that when this mirror was in
|getting  re-aluminised a malfuntion in the vacumm pump caused silicon oil
|to be  deposited  in a fine film accross the mirrors surface...... .... It
|has proven exceedingly dificult to remove that film of  oil to the
|molecular level... the significance of which is demontrated by  the
|unwillingness of any subsequent coatings to stick to his  mirror for any
|longer than a few weeks......you can in fact rub the coating  off with  a
|gentle rub of a finger....!!!!!!.....         Last time I heard he was on
|his 6th coating.......... Regards
