Behold the hairspray method from the vogue forums. On the thread, Nightlily says:
"Before you wear them... spray them with a few coats (over the course of a few days, so they dry thoroughly inbetween) with a strong hold HAIRSPRAY!
Apparently it sort of creates a protective shield over them. I can't say that it stopped them flaking entirely, but I believe it certainly helped! I used a super super sticky/thick hairspray called "Membrane Gas" from Fudge. Didn't smell great, but it sure did the trick! The shoes I were treating were bright red, and bright gold... and neither were adversely affected."
Having the shoes drycleaned is also mentioned. And on the forum, Miranese says:
"I always spray satin shoes with a waterproofer while they're still new. I wait 24 hours then re-spray. I find that this helps keep the dirt at bay. If they do get dirty, I use baby wipes to clean the surface.
However, there is not much you can do in case of rain. No amount of waterproofing will protect them in the long run."
At Le Chateau (ooh la la) there is the following advice:
Use a Nylon Stocking to clean the surface.
● Slip a nylon stocking onto your hand
● Gently rub the dirty spots in a circular motion
You can use the same procedure on all your stained satin clutches to remove dust and dirt. So simple and so great!
Sounds good to me. The only aerosol hairspray I had in the house was John Frieda's Moisture Barrier. So I used that.
On the left is the shoe without spray. On the right is the shoe just after spraying it.
Day 2 - I sprayed the shoes 2 days in a row, letting them dry 24 hours in between. Today I sprayed on Kiwi Protect All as a final protectant. They are now darker than the original color, but I love them. I don't know if the satin quality or color will determine whether hair spray darkens the item. Or perhaps using the right hairspray will ensure that the color doesn't change. I admit that I sprayed up close and could have probably been 6" or more back. That might have been a factor in color change.
I liked this experience. Esp since the shoes were only $12.99. I cannot imagine doing these to a pair of J Crew flats at $98-$150/pop. I would feel awful if the color changed.
In the comments of this post, Francesca adds...Here's a tip I picked up at the purseforum.com where I used to lurk until my obsession shifted to Crew:I use a waterproofing spray called Vectra Spray. It's a non-aerosol pump that sprays very finely and doesn't change the color or texture. I've used it on very expensive, ultrasoft handbag leather as well as fabric shoes and it works great. Also spray it on my white jeans after a laundering to keep them looking clean longer -- it really does repel liquids & stains -- I'm on my 5th wearing of these jeans and they're still smudge-free."
When I looked for Vectra Spray, I came across another recommention by Apple. It looks like the Apple Rain & Stain Formula might be good on satin. However, it's specifically recommended for leather so I'd email to ask before using.
