Argh, greasy handprints.

Whatever you do, don't try scrubbing it with a brush. Been there, done that. Leave's a nasty scar to say the least.

If I had to do it again, I would try a foam cleaner and a micro fiber cloth and attempt to blot the stain's up rather than scrubbing and or rubbing.

I usually use Tuff Stuff, but had bad luck trying to remove a mud stain from the headliner. Probably not as bad as grease, but I think you will get my drift.

 

dawn dishwasher detergent/
works for me/
you don't want to soak everything, just a little bit on a slightly wet rag//

 

What about the screen on the display. looks awful.

 

Certain types of brake cleaner work very well. Test first in an inconspicuous place.

 

Was picking up a new 16 model 4, it of course needed to go back in the shop to get "re-calibrated", came back to me, grease here and there and everywhere, waiting for the toyota questions about my buying experience, I have two words "Insanely Unprofessional"

 

Dawn in warm water and soft cloth and rinse should remove it. Dry, then wax to protect afterwards.

 

Oxy foam. Apply and lift dirt off with another towel. I merely tried one area to see what all the fuss was about and straight away realized even wiping the headliner causes issues in the grain of the material.



LG-H901 ?

 

You're right, not a wax, but I mean a fabric protectant like Scotchguard.

 

Did you try contacting the place? Maybe they would spring for an interior detailing service?

The manager might even appreciate the call; if they're on the ball they'll want to hear about negative experiences, remedy the problems.

 

Unfortunately IMO the cloth trim in The Prius is not the most durable. It's frustratingly thin.
So I would agree with trying Dawn...and using the gently blot method.
A wet/dry shop vac, that might allow you to blot, and vacuum straight out, might be helpful.
But I would also not recommend heavy scrubbing.

If it was grease, oil, dirt...you might have better luck with Dawn than you think. It should be cleanable.

Pretty unprofessional of the Firestone tech.
You could complain, and they might be willing to accept responsibility and do "something".
BUT...I think I'd try to fix it myself first, as I wouldn't necessarily trust what they might try to do. Too strong a chemical or too aggressive an approach and you can make it worse.

 

Chap,

IF you do DIY, remember don't rub or scrub. Blot ONLY. Otherwise there will be a scar.

Good luck!

 

THIS.

If someone did that to my car, I'd demand they have the stains removed by a professional cleaner at their cost or I'd see them in court.

Heck, I've blacklisted a state inspection center because of how much a mess they made while inspecting my car (and worse).
