Vanish Kosla Stain Remover Spray Left White Stains on My Couch

I used Vanish Kosla Stain Remover Spray on my couch to tackle a few spots, but instead of removing stains, it left white marks where I sprayed, which now won’t come out. This is incredibly frustrating, especially since my couch was a significant investment, and the spray is marketed as safe for upholstery. I now have visible white patches that look worse than the original stains. To make matters worse, I have guests coming tomorrow, and my couch looks ruined. I expect Vanish to take responsibility for this issue and provide a solution immediately. This product should not be damaging furniture—it should live up to its promises!
