Both my mom and I have silver cars with the grey interior (I have my GS, she has the LS460L), the color looks great, but the floor carpet shows the dirt like none other. Any recommendations on products that can help keep the grey carpet clean and looking good?

 

get a little HEATED portable green Bissle.
Those little machines are wonderful for carpet cleaning.
Or you can spend a little more $$$ and get a portable dry cleaning system that is wonderful as well.
Bissle = $150.00 plus chemicals, the dry cleaning system is a few hundred.

 

If you are referring to the carpet floor mats, get some all seasons. At 1st I didn't like them and didn't think they would go well with the all grey interior, but now that I have them I don't worry about getting anything dirty anymore. Jump in and drive.

 

I have noticed some people get their mats wrapped in clear plastic; it keeps them looking brand new. I have a clear plastic sheet with small studs on one side cut to the same shape as the mat; it does the trick too and is easily removed for cleaning.

 

i stick some aftermarket cheapo mats in there to keep the factory mats clean. then for special occasions when it' s dry out i take them out.

 

I use a product called FOLEX (instant carpet spot remover). Spray it on a stain and swirl it around with your fingers (non-toxic, odor free, non-flammable) and blot with a lint free cloth and your through.
