Use OPI brush cleaner on Powder Perfection Base Coat and Top Coat brushes that have hardened over time. This brush cleaner will revive hardened brushes back to their original state. Made in the USA.
Remove the Brush Cleaner's cap and place your hardened brush into the solution.
Close cap tightly. Let the hardened brush soak in the Brush Cleaner for five to 15 minutes, depending on the amount of product build-up.
Cleanse the newly restored brush with N.A.S. 99 and allow to dry before using.
