Toilet Cleaner & Descaler is a macerator & septic tank safe formula for general, every day cleaning or deep descaling. The phosphoric acid based, bleach-free formula breaks down limescale, dirt and grime, leaving a fresh ocean fragrance. Our solution is a saniflo descaler cleanser alternative. It can be used in any macerator system without damaging seals, unlike bleach-based products. Descaling the macerator toilet system regularly is important to prevent damage from scale build up and blockages. So, we made an easy to use, safe toilet cleaner to prolong the life of your toilet systems.
