I purchased some fine suede boots from PB and forgot to spray-protect them. Wore them and spilled butter on the toe part. Found put next day and was horrified- the butter had soaked in. I tried baking soda a few times and it reduced the stain, but it was still visible. I ordered this suede cleaner, followed instructions and my boots are back to brand new- a month after the butter soaked in and it saved my boots. My new holy-grail for suede.
Never used this brand before but it works great!
