Flip open the lid. With dry wipe in hand, cover the dispenser button and press down. This kick-starts the dispenser and distributes warm water on your wipe.
Warm water will spray out as long as the button is pressed down. Push as many times as needed to get the required amount of water, then wipe away to your heart’s content.
This one doesn’t get on well with dishwashers, so hand wash with warm soapy water only.
