Ok bro now thats a good thing that you want to learn and clean cars are what attracts. I agree with @vdr6367 he is right.! first of all don't ever install raxene, the reason is it will every time you sit in the car it will be damn hot due to raxene. Carpeting is the best option go for that put up carpet matts and plastic matts on that. the reason is water spilled or muddy shoes won't distrub your carpeting and will be safe from getting dirty. I have a liquid carpet and upholestry cleaner if you want that i can give you , that will help you remove the dirt easily and your floor will be clean as new if you use that on regularly i mean once in a week. That will do your job.
