Using this soap dispenser is easy. Just fill it from the top with your preferred universal bulk foam soap. When someone places their hand under the dispenser, it will automatically dispense the right amount of soap thanks to the portion control feature. For maintenance, regularly wipe the dispenser with a soft, damp cloth to keep it looking clean. Avoid using harsh chemicals as they might damage the matte black finish. Check the soap level frequently and refill when it's low to ensure continuous use.
