Passivation Metal Descaler – Mild Acid

Mild acid chemistry. Uses mild-acid, non-abrasive chemistry for mineral-deposit removal; test substrate compatibility before full application.

Non-abrasive formulation. Preserves the passive chromium oxide layer on stainless steel that provides corrosion resistance — aggressive abrasive cleaning destroys this layer, accelerating long-term metal degradation.

Variable descaling strength. Use approximately 100–250 ml/L according to mineral load and substrate; start low and increase only where scale severity requires it.

Food-contact rinse requirement. Thoroughly rinse food-contact metal surfaces with clean water after application before returning equipment to service.

Institutional substrate range. Stainless steel, chrome, and treated aluminium — the core metal surface types in healthcare, industrial, and educational catering facilities.

Light mineral film. Start at approximately 100 ml concentrate per litre of water.

Moderate scale. Use approximately 200 ml/L.

Heavier compatible deposits. Use up to approximately 250 ml/L after a substrate test, then rinse thoroughly—especially on food-contact metal.

Compatible equipment. Acid-resistant trigger sprayers or low-pressure pump sprayers, together with soft cloth or non-abrasive pad application.

Use conditions. Use dedicated acid-compatible containers, seals and spray components. Apply a controlled coarse spray rather than a fine mist.

Not intended for. Not intended for foggers, aerosol generators or equipment with wetted parts that are not rated for acidic cleaners.

Why does mild acid restore stainless steel brightness, and what is the passive layer that makes this possible? Stainless steel’s corrosion resistance depends on a passive layer — a microscopically thin (2–5 nm) film of chromium oxide (Cr₂O₃) that forms spontaneously on the steel surface when exposed to oxygen.

Working range. A 5 L pack can dose roughly 20–50 L of water across the 100–250 ml/L working range.

Use strength only where needed. Descaling is an intermittent corrective task, so dose should follow actual mineral load rather than a fixed everyday concentration.

Material check. Acid strength and dwell time should be checked on the actual stainless/chrome/treated-aluminium substrate.

Acid handling. Mild-acid concentrate; gloves are recommended and splashes to eyes or skin should be avoided.

Metal compatibility. Test first on reactive or decorative metals including copper, brass and unknown alloys. Never mix with chlorine products or strong alkalis.

Storage segregation. Keep tightly closed in the original compatible container and store separately from chlorine products, alkalis and incompatible metals.
