Any way to get out dash scratches?

That's going to be difficult IMO.

Here what I'd try in this order.
Interior detail spray..one with soft rag in directions of scratches.
Lemon Pledge (furniture cleaner not joking).
Silicon grease with an Q Tip
Small foam polisher...last resort as this may make it worse forcing a replacement.
As a final resort I'd take sand paper to it, yet then you some how need to get the grain/ texture and gloss/ sheen back into it and I don't think that would work.
Those are my thoughts.

Best I think you may get is adding a little "make up" to cover it, yet it may still be noticeable.

Maybe place a Prius sticker or pinstripe design over it/ repaint then entire panel?

Else you'll have to replace if it "bugs" you.

If the scratches came from your shoes when exiting the car....it happens to all of us with any car.

Enjoy your ride!

 

If there's a drvinyl.com franchise near you, it might be interesting to ask them for a quote. I'd be interested in what they say.

They have a franchisee near Indianapolis whom I found hard at work in the used lot of a Toyota dealer ... he was the guy they hired to fix similar stuff up. He was equipped to recreate the grain of grained plastic.
