getting spots off of speedometer plastic

How do you get little white/grey spots off of clear plastic.

Especially when there is no reason they are there!


I have my speedometer cluster out so now is the time to clean it.

It has a clear plastic window in front that at the top is just about
vertical. Further down it curves around to 30^ from vertical, and the
more it approaches horizontal the more spots it has. As if they are
caused by something that falls. Otherwise, the plastic is like new,
totally clear, without a scratch, and even wheree the dots are, I can't
feel anything. 2005 Toyota.

Rubbing with a watery rag does nothing, rubbing with my finger does
nothign also.

Greyish spots one millimeter or a little bigger.

What are they?

What are they from?

I spit as much as the next guy, but I don't remember ever spitting in
the car at all, and certainly nowhere near hard enough to reach the
speedometer. So where did this stuff come from? Even in the rain with
the convertible top down, it's not going to get rained on.** what made
these spots?

And, most important, how should I get rid of them?



**Sometimes I drive in the rain with the top down, but even I don't get
wet, so how could the speedometer get wet. And I've done that only for
5 minutes in this car. (In an earlier car I drove for an hour until
the rain stopped. Get a few drops on the top of the rear seat, but
everything else stays dry. The harder it rains the faster you have to
go to keep dry.

Try toothpaste. Contains mild abrasive but will not harm plastic. Also
about 15& isopropanol is used to clean acrylic but do not use any pure
solvents as acrylic is soluble in many.

I would try windex or such first.

Too bad you have me blocked. The stuff works great on helmet face shields.

See, but you STILL can't stop driveling in your known verbose manner! It's
obviously completely out of your control. Your gob has a life of its own.
LOL

So if it wasn’t clear, we are guessing it is a kind of scratch on the plastic, like how headlights get fogged and need to be polished. I would have guessed fingernail polish remover, but one guy here thinks it’s too strong.
