The BrushEgg is made out of silicone and has two different surfaces, smaller knobs at the top and groves. The smaller knobs are used for foam and lathering and cleaning of smaller brushes while the groves are used to agitate the bristles just enough so they release product build up and dirt and are perfect for cleaning bigger brushes after you lathered them up
How to use the BrushEgg
Step 1 – Wet makeup brush
Step 2 – Apply mild cleaning solvent like shampoo or liquid hand wash on the BrushEgg.
Step 3 – Twirl your makeup brushes around to lather them up on the smaller knobs.
Step 4 – Move the brushes from side to side over the groves to get rid of stubborn dirt.

Step 4 – Rinse with clean water and let your brushes dry on a flat surface.
