Does anyone know how or what products to use to clean the headliner on the 2006 is350. I believe it is alcantara or suede, I'm honestly not too sure.

 

I recently helped a friend get some stains out of his suede seat by very gently blotting the stains with a clean microfiber, warm water, and a very small amount of Woolite Delicates. NEVER rub the stain, as it can damage the materials further, as well as spread the stains. Be patient and start with the outside of the stains, then work your way in, that way you don't spread it. Also, be sure you change spots on the towel regularly. Once the stain is gone, blot with a little warm water and let it air dry. The key here is to be very gentle and mix the Woolite into the water, not directly on the stains.

 

So you dip the microfiber in the woolite+water mix and then blot it on the surface?

 

Correct. We started with a very small amount of Woolite in the water, and then slowly worked up the amount while working the stains out. Best to start as minimal as possible. I'm sure there are better methods and cleaners out there, but this got rid of about 80-85% of the stains for us.
