The Brush & Sponge Cleansing Gel by Real Techniques is a must-have for anyone who uses makeup brushes and sponges. According to Tara, cleaning these tools can be a chore, but this product makes it easy and effective. She simply added a drop of the gel to her mat and sponges, squished them around, and rinsed them clean. The result? Super fluffy and brand new-looking brushes and sponges. The gel dried quickly and had no scent or fragrance. With a 4 oz bottle, it will last a long time as only a small amount is needed. Overall, this cleansing gel is a great investment to keep your brushes and sponges free from bacteria and product buildup.
