Grab your old thick polish
Remove the brush.. Yeah it looks gross :/
Grab your remover or thinner. Thinner is preferred so you don't get bubbles in your polish.
Pour about a teaspoon in the polish.
While the remover sets in grab a cosmetic sponge.
Wipe off your brush :)
Now wipe off the top.. It will be nasty :)
I even took a tooth pick to the crevices.. And this is what I removed..
Place the brush back in the polish
This is the way you should always prep your polish. Shaking your polish creates bubbles, no one likes bubbles in polish :/ Here is how :)
