T.F.
Is it Coach? I have a white Coach that I think the outside is nylon. It is available in a tan, white and black. Super cute but easy to get dirty.
I was told by the Coach store at Stonebriar where I got it that if soap and water did not remove the stain, to use a little alcohol. I was told not to use the Coach cleaner or Scotchguard on it.
I have used the soap and water on a wipee and that has helped keep it pretty clean. There are a couple of dirty spots on the bottom and I have used the alcohol with success.
Just this week is left to use this purse since Labor Day is coming up. I might try the hairspray as well before I clean it up and store it until spring.
Good luck.
