I bought a 1998 camry le 4cyl. and it has some stains in the interior what is the best method to get these out i have no clue what they are?

 

as i've read in a previous thread, you can use simple green sprayed directly on the stain and rubbed with a clean cloth.

 

I'd probably start with a Carpet & Upholstery Cleaner spray... I do like Mothers, but there's lots of brands out there that are formulated for fabrics and carpets. One reason I like Mothers is I can spray it on a clean water-dampened towel and also wipe the vinyl.

Then if there's a greasy spot that looks like it needs a degreaser, then (and only then) I'd think about using a degreaser, and in that case I'd rinse and follow with the more appropriate cleaner.
