I'm currently working on a Rarity plush, and so far she looks amazing. There's one issue: Even though I wear gloves during the process, white picks up every speck of dust in the room, and collects oil faster than the bottom of a McDonald's fry container, which had been stressing me out like mad, since Rarity is white, not a drab off-white gross...thing. Considering how many of us in the fandom have white plushies, I figured I would pass the word along.

After pouring over the internet hoping to find some source of hope, I was able to find the magic ingredient that fixes all collected grossness, and it's something almost everyone should have in their kitchen.

Baking soda.

Seriously, that's all it takes to get your white plushies to (proverbially) sparkle like the day you got it. I've tried the technique on one of my test plushies, and it worked like magic. The result was staggeringly simple.

• Stick your plush in a pillowcase that you are positive won't leak any dye onto your plush, because that would suck
  
• Dump in a goodly amount of baking soda (depending on the size, 2 tbsp for a 5 inch tall plush, going up from there), enough to give the plush a good dusting all over its body
  
• Tie off your pillow case
  
• Shake! I usually shake for about 3 minutes pretty vigorously
  
• Let sit about 10 minutes, more depending on how badly soiled it is
  
• Remove plush from pillowcase
  
• Dump out the baking soda from the pillowcase
  

Optional:

• Turn pillowcase inside out
  
• Put plush inside the inside out pillowcase
  
• Tie a knot in the pillowcase (No escapees!)
  
• Toss that sucker into the dryer (Use a dryer sheet if you so desire)
  
• Only leave it in for 2-3 minutes
  

The optional bit will fluff up your stuff(ie) just a bit, but isn't required for cleaning

Now you want to get out as much of the baking soda as you can. Much like beating a rug (sorry Rarity!), you don't want to do this too hard, but at the same time you want to make it so you don't get covered in white powder every time you give your plush a squeeze. Once you get all the excess, you're done. While it won't be the same as when you got it, it shouldn't be as dingy anymore. Just be aware before you start that not all plushies will make it through this process. Make sure that all the seams are strong enough to withstand a toss or two in the dryer.

Additionally, if you feel so inclined, you can unstuff your plush if you have sewing ability, soda your plush, and restuff with new, fluffy stuffing. Make sure you know how to do this before attempting to do so. This involves not only sewing, but you should know how to stuff a plush. It's not as easy as it seems. (seams? Haaaa.)

Anyways, that's all! It shouldn't take more than 15 minutes.

A couple of notes:

This is not a method I came up with, but because it was so useful, I thought other people could use it as well.

I have no tested this on any color other than white. I may work, I just don't know.

If for whatever reason your plush gets screwed up in this process, it's not my fault. I'm just passing the word along.
