Descaler - Washroom and Hospitality - Sierra - Image 1
Description

Descaler is a phosphoric acid descaler for limescale in commercial warewashers and kitchen equipment. Sold in 5L jerry cans and 20L drums.

What it does

Hard water leaves lime on elements, spray arms and tank walls, which cuts wash performance. Sierra's Descaler is a concentrated acid (orthophosphoric acid above 40 per cent, pH about 1) that breaks down limescale, calcium and rust along with other mineral scale. Its data sheet names it a scale remover for commercial warewashers.

Where to use it

Commercial dishwashers and glasswashers, plus other commercial equipment and systems that build up hard water scale. For the daily wash chemical in the same machines, see Supa Dish Ease Machine Dishwash, and browse more kitchen lines in Washroom and Hospitality.

How to use

  1. Follow the machine maker's descaling procedure and dose by the label. Sierra's sheets we hold give no ratio.
  2. Wear chemical goggles, a face shield, elbow length gloves, an apron and rubber boots.
  3. Drain any caustic wash chemical from the machine first so acid and alkali never mix.
  4. Run or soak the descaling solution until the scale has dissolved.
  5. Flush the machine with plenty of clean water before the next wash cycle.

Safe on / avoid

It is made for scaled up warewash equipment. The data sheet warns it may corrode metals and lists glass, leather, natural rubber, strong caustics and some alloys as incompatible, so do not leave it standing on glass, seals or unknown fittings, and rinse well. Test a small area if unsure. Read the Safety Data Sheet before use.

Questions
▸What is a descaler used for?

Descaling dissolves the lime that hard water leaves inside machines. This one suits commercial warewashers and similar equipment.

▸Will it remove limescale and rust?

Yes. Sierra lists limescale, calcium, rust and other mineral deposits as what it dissolves.

▸How often should a commercial dishwasher be descaled?

That depends on your water hardness and the machine maker's schedule. Our sources give no fixed interval.

▸Can I buy descaler online and have it delivered?

Yes. Order on this page and it travels as dangerous goods freight to sites across Australia.

▸Can I mix it with my dishwashing detergent?

No. It is a strong acid and the data sheet lists strong caustic materials as incompatible, so flush one out before using the other.
