I'm in the kitchen when my husband walks in with a gallon of Krud Kutter he says, "try this and tell me how it works". For a whole 2 days I'm watching the gallon like it did something to me, I'm saying to self, it better work. Finally, I cracked it open made a spray bottle with that and tap water I sprayed it along the floor boards of kitchen got down and started scrubbing with force. I realized, there was no need the Krud was already lifted and gone. I use it on everything. I even put some in a load of clothes a load of rags my husband uses to work on his bikes with they were white rags. Let me tell you I do not want to buy bleach no more!!!! It got my whites whiter and colors brighter....if they made some for washing clothes I will never buy bleach again..... THANK YOU KRUD KUTTER I LOVE IT!!!
