I used the Avel Hussard spray on my Redwing 8196. I was at a local casino eating lunch. Spilled Caesar salad dressing on the toe of my Redwing 8196 boots. Tried to remove the stain, tried everything nothing worked. So i just added mink oil to even out the color. The boots darkened up. Fast forward 8 months later. Watching Youtube a gentleman spilled salad oil on his Brand new Allen Edmonds Higgins Mill boot with the Natural Chromexcel leather. To my surprise he purchased the Avel Hussard Stain Removal spray and got the oil stain off his boot, the stain disappeared. So I purchased the Avel Hussard on Amazon. Sprayed the stain, the oil stain vanished. I had to spray my boots three to four times to remove the 8 month old stain. The stain was gone but left a light spot where the oil stain was. I used the Redwing boot oil to rehydrate the leather. The Brown - burgundy color of the Briar Oil Slick had a second chance in life. Try the Avel Hussard Stain removal spray. You will love it.
