[TR] Retr0bright update

[auprichard at uprichard.net (Andrew Uprichard)]

I posted recently about the possible benefit of Retr0bright on the washer
bottle.  Well, I am glad to report the same mixture had a dramatic effect on
the non-return valve from the servo.  Started off almost brown and, after 2
applications, is - well, not the pearly white of my kids' teeth, but along
the lines of the wanna-be-white of mine.

 

Oh, and this is one part (the non-return valve) which is not as readily
available as the washer bottle.
