I have a Pure One Flow Radio. This model has an odd finish, which is
like a soft touch matt. After several years- I'm not sure how long I've
had it- I bought it when Comet were closing down so a good few years,
the finish looked really grubby. I used my usual foam cleaner without
any real joy. Then I tried some alcohol which has removed the finish to
show a shiny finish over most of the case. No real problem, if I can
remove it all. In fact, it will look quite smart, if not better than
before.Â* Looking on the internet, it seems this is a known problem with
this radio.

Someone has suggested that Tea Tree Oil is the 'magic' way to remove the
odd finish. I've only heard of Tree Tree Oil being used for cosmetic
purposes.

Has anyone tried it as a solvent or does anyone know if there is a
solvent mixed with it?

It is quite likely cut with a relatively inert non-toxic oil.

Limonene is another pretty good general cleaning solvent extractable
from lemon rinds which is why microwaving a lemon cut in half in water
is quite a good way to clean the interior of a microwave oven.

I found old brake fluid remarkably good for removing gone horrible tacky
soft vinyl plastic finishes off things that had degraded.
