WC-Ente Active Clean is a toilet cleaner that foams and powerfully cleans the toilet. The drop-shaped toilet cleaner produces four times more foam compared to WC-Ente Aqua Blue after flushing and provides a pleasant freshness throughout the bathroom - suitable for all rimmed toilets. Ensure that the toilet is clean before hanging the toilet block. Unfold the toilet hanger and attach it to the rim of the toilet. Position the product so that it is in the water flow during flushing. Remove and dispose of the product once it is completely used up. If possible, recycle it.
