Plunger Urinal Tablets are formulated to prevent limescale and urine stone deposits from building up and to ensure hygienic freshness. Water soluble tablets contain microorganisms which degrade organic substances both in the urinal and in the pipes autonomously. They also contain a high-quality perfume oil that is released when it is exchanged with liquid and pleasantly deodorizes the air in the room. Using Plunger Urinal Tablets on a regular basis noticeably reduces unpleasant odors and buildup.
