So, the inside of my Nicola flats were looking yucky and I wanted to clean the Legacy Stripe Lining in them. Asked hubby to get both Shout Wipes and a Tide pen at the grocery store to test them on cleaning. Well, he couldn't find those, but brought home something called "Stain Pen", www.stainpen.com. It goes on like a roll on deodorant. I tested a spot first for colorfastness and it seemed safe, so I went ahead. First, don't get this on the leather, only on the fabric. I rolled it on the fabric area (it kind of comes out like a gel), then used my fingers to rub it around and rub it in. Next, I took a dry wash cloth and rubbed the fabric and got quite a bit of dirt off. Then I rolled the gel stuff over it again, used my fingers to rub it in again, and let it sit for about an hour. After the hour, I wet the corner of a washcloth with cold water and rubbed it on the fabric. It took out the residue cleaner and the rest of the stains! I wish I had taken a before pic, they look great now. After wiping with the wet corner, I did wipe again with a dry corner. They are now drying over night and I will spray the inside with ScotchGuard tomorrow to protect them.
