Talk about fighting fire with fire. Most of us would find it silly, but it actually works. At least to some extent. When disaster strikes, the best approach is to use a store-bought red stain removal solution. If stain removal solution is nowhere to be found (just like rubber bands in the kitchen), the second-best solution is to go for white wine.
Surprisingly, white wine is effective in diluting red wine stains. Just soak the stained garment into white wine for a few minutes before washing it.
