How do I get red wine out of white denim?
Simply apply the Stain Solution directly to the stain. For an extra boost you can add the All-Purpose Bleach Alternative, mixing it with the Stain Solution to create a paste and working it directly into the fabric. Allow the denim to soak in a hot water bath- the longer the better. Once you are satisfied with the stain removal you can then go ahead and launder as normal.
I've linked below our recipe on washing denim.
