The industry's hottest ultra-powerful prespray uses state-of-the-art nanotech “micro-robots” to bind and suspend soils for fast and efficient removal. A complex buffering system keeps the pH stable, plus its new Hydrocoating Technology means it's fast-dissolving even in cold water and stable up to 212°F / 100°C. The RTU will not separate and can be stored for several weeks. Ultrapac Extreme is not just for carpets - use it on tile and grout and be amazed by the results.
