Thats because water is not a lubricant.jeremy wrote:My drivers side BX window was slow and reluctant to move from the day i got it some 6 1/2 years ago. I've been squirting it with silicon ever since and it lasts about 18 months between sprays! What surprised me was that it seemed slower in the wet than the dry - and I would have thought the water would have acted as a lubricant on the rubber.
In fact on some surfaces it can have the opposite effect, and cause more friction.
I remember reading some years ago about a spray on cleaner/lubricant for records that was supposed to improve playback noise, and the people testing it did microscope examinations of the surface of the LP after playing it.
The result was the spray on lubricant did seem to work and help clear out dust particles. Then as a control experiment they tried "lubricating" the record with the same amount of water. Result ? To their surprise the microscopic amount of water actually caused the needle to tear the grooves of the vinal to pieces - not visible to the naked eye, but seriously damaged when viewed under a microscope...
None of the other conventional thin lubricants they tried did the same damage as water.
(Non car related moral of the story - if you wash records never play them until they're completely dry
