Using flour combined with chemical R69.96 Wheat flour is also used by many people in this case. We will mix 1 cup of flour with about 3 teaspoons of R69.96 solution. Then mix well and add water until the mixture is thick like yogurt. Apply the freshly mixed mixture to the yellow stain. The thickness of the mixture applied is about 5mm. Then we also use food wrap and tape to wrap it up. Wait for 6 hours, then also take a paper knife and a damp rag to clean the flour from the floor.![]()
