Faucet friend.

Put your faucet to work! If you’re not a fan of suction cups, try this faucet-hanging sponge storage method. The rubber grips protect your faucet while simultaneously preventing any slipping or sliding.

The "double" option offers enough room to hold both your wool sponge or scrubber on top and your regular sponge below. The best part is that water drains right back into the sink, where it belongs.
