I haven't cleaned it yet to review that. However the water comes out so clear you can barely tell it's there except the magnification it causes. Plus you can see all the gross stuff left over after the first use.My major complaint with this product is that it has no off button or switch and has to be plugged in and unplugged between every use. And it has a carry handle on it but it on the lid which doesn't lock on so it's just waiting to fall apart and dropped whe being carried.
