Authentic HP85 color?



#5

Hi.
Which is the authentic HP85 plastic color?
I have found pictures in which it looks totally white, others almond and others light beige.
My HP85 is dark-yellow!. I have taken a look behind the cap and the color there looks light beige.

Then which is the true color of HP85?


#6

Hi,

If my memory serves me well it was clear beige right out of the box...

(It was in 1982 though... :-)

A previous thread also deals with this trouble here.

Cheers and good luck with the colour recovering.

Diego.

I have used a single product:

http://www.amazon.co.uk/Vanish-Oxi-Action-Power-Foam-600ml/dp/B003VALYPG

I have applied this product alone, no other product mixed with it.

Before testing the product on the whole case, I have tried putting a small drop on some hidden part. Two hours after, the circle under the drop was clear beige!
Then, I have taken appart the HP85, and have covered the upper side with a thick layer of Vanish-Oxi-Action foam. Couple hours later it was clear beige. Not exactly the tone at the bottom side but almost there. It was a little darker. Probably the process could be repeated to clear up the tone even further but it has done a wonderful job! Probably it would work as well in less than 2 hours.


#8

I haven't used this product on a calculator but I can attest that the Vanish soap bar frothed up with a little water makes a good job of removing nicotine stains from the vinyl covering on old radios (and a better job than expensive foam cleaners on the cloth upholstery of car seats).
