Wondering if anyone has good recommendations on how to clean the upholstery?

My passenger side looks like someone with dirty fingers has been touching the visor area.
Wondering what is the best way to get it out?
Top of my head is thinking normal laundry detergent mixed with water and using something like a toothbrush to clean it?

Any other (better and proven) ideas?

 

I'm no expert, but I like OxyClean for a lot of this type of thing.

 

Problem with that approach is you can't rinse it back out.

Go to HomeDepot. Buy some Folex. Spray on, you can agitate with finger or brush, Blot off. No rinsing, no smell, just clean.

 

Folex? Ok I will try that! Thank you.

 

FYI, you can get a gallon size of it if you go to the back of the Home Depot where the carpet cleaners are. Better value.
