How about removing blueberry stain (it turned reddish when dry) on black synthetic Mazda Sedan auto seat?

Answer: Not to worry! Generously and evenly spray the area with a BISSELL-oxygen based product such as OxyPro® Stain Remover for Carpet or OxyPro® Pet Stain Remover for Carpet. Gently work the solution 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.

To clean the soiled area, use an upright deep cleaner such as the Lift-Off® Deep Cleaning System or the ProHeat 2X® Pet with a BISSELL upright deep cleaning formula such as BISSELL 2X Professional Deep Cleaning Formula, Deep Clean & Protect or 2X Pet Stain & Odor Formula.

If you are using a portable deep cleaner such as the BISSELL Little Green® or the SpotBot® Pet portable deep cleaner, use BISSELL OXYgen BOOST, Pet Stain & Odor formula or Spot & Stain.
