Ever since the bb and cc cushion compact exploded on the beauty scene, the nagging question has been how to keep the sponge clean. Advertised as the key component to making cushion makeup so flawless, the sponge here is usually different than your average latex or foam applicator. Thin and delicate, the material should not be rubbed or squeezed lest you tear a hole right through it. Been there, done that.
In fact, most brands will tell you simply not to wash it but replace it with a new one. But fear not frugal beauties, there is a time to save and a time to spend but washing your bb cushion sponge is absolutely okay in my books.
