This 3-in-1 multi-purpose brush is an excellent kitchen cleaning tool that can firmly wash every corner, including the lid and drinking mouth of water bottles that can be very hard to reach. It features 2 smart brushes. The corner brush which is cut diagonally is perfect for brushing uneven shapes that are hard to reach with sponges, and the gap brush on the other side is great for cleaning narrow grooves and squeezing out dirt. The brush also includes a built-in packing or lid remover for lids that are difficult to remove with hands.
