With a 50/50 mix, the solution eventually cleaned some spots and stains on white upholstered dining chairs. Was surprised I had to use this product about 3 times for these spots. With a 50/50 mix, the solution did clean yellow bile stain from dog vomit on carpet when I found it right away. However, this solution mix has not removed yellow bile stain found after a couple of weeks. This is very disappointing after reading all the reviews. I have tried to remove this stain 3 times leaving the 50/50 mix on the stain for several hours and followed up with rinsing and removing water using my carpet cleaner.
