My husband was using my Nissan Maxima to haul tires and the liner and seats are stained. Some stains may also be fixing a flat but, the head liner now has black marks from the tires?

Answer: These stains may contain grease.  Try applying BISSELL Tough Stain Pre-treat for Carpet & Upholstery to the stain to loosen up the grease before using your upright or portable deep cleaner.  Work the Tough Stain Pre-treat into the area with a small brush, sponge, or cloth using light strokes from the edges of the stain to the center.  When you reach the center of the stain, lightly pinch in an upward motion. Do not rub the stain.  Wait 5 minutes.  Then, use your BISSELL upright or portable deep cleaner over the affected area.

If any stain remains treat it with OxyPro® and let stand overnight.
