Step 3: Remove the bonnet

The faucet handle isn't the only thing between Richard and the cartridge; he must unscrew the bonnet——being careful not to scratch this chrome cover for the cartridge assembly—with a pair of slip-joint pliers. Then he uses needlenosed pliers to grab the U-shaped retainer clip, which slides through the faucet base and around the cartridge to secure it in place. As he takes out the pieces, he carefully lines them up to the side so he's sure not to lose anything or mix up the order of the parts when it's time to reassemble the faucet.
