IMMACU-10!!! I just took a coffee stain out on Sunday and I didn't even do much more than spray it on. This is an ENZYME based product NOT chemical. I use it for EVERYTHING...laundry, windows, floors, carpet, upholstered furniture, etc.
You CANNOT buy this in stores. Don't know where you live, but I'm in Fishers. Let me know where you are and I can give you some direction in finding it.
Costs $20 for a quart that lasts FOREVER because you normally dilute it - 4 small capfuls to a quart of water. A few things I use full strength - took blue paint off my eggshell colored car WITHOUT taking off the original paint job!
Anyway.....let me know.
