selvyt

[Mark Mandel]

My sister drew my attention to this word on
http://www.lacywest.com/t_watch.htm "Battery Change Procedure - Lacy West
Jewellery Tools and Supplies":

Step 2  Clean the outside of the watch with a selvyt, at the same time
checking to see how it should be opened.

OED Online has
>>>
[An arbitrary name.]
    A kind of duster or polishing cloth.
1891 Patent Specif. No. 21,399. 1898 Cycling 76 Plating is best cleaned of
rust by hard rubbing with paraffin and polished with chamois leather or
Selvyt.

So it's a registered trademark. Now compare these entries:

>>>

Kleenex

    The proprietary name of an absorbent disposable cleansing paper tissue.
Also attrib.

===

Jell-o, Jello
Chiefly N. Amer.
    The proprietary name of a powder used to make a fruit-flavoured gelatin
dessert; loosely (with lower-case initial), jelly*
[*Not US "jelly"]

===

Kodak, n.
    The proprietary name of a range of cameras produced by Kodak Ltd.

Shouldn't OED label this one "proprietary" too? Or is there a distinction
that I'm missing?
