DESCALING LIQUID 25 LTR

Description

Unitor™ Descaling Liquid is a highly effective hydrochloric acid–based cleaner formulated with corrosion inhibitors to safely remove scale, rust and mineral deposits from a wide range of marine and industrial systems. The product is designed for heavy-duty descaling operations where fast, deep cleaning is required—such as boilers, heat exchangers, condensers, evaporators, and cargo hold surfaces.

This powerful descaler breaks down stubborn scale, rust layers, cement residues, lime wash, and cargo sediments commonly found on bulkhead coatings and internal process equipment. When used together with Unitor Cargo Hold Cleaning Kits or the Unitor Chemical Cleaning Unit, the solution delivers even higher cleaning efficiency for large systems and challenging deposits.

⚠️ Not suitable for use on aluminium, zinc, tin, stainless steel, titanium, or galvanized surfaces. A special cleaning grade must be used for these materials.

Safety Notes

Descaling operations produce gases such as hydrogen and carbon dioxide. Ensure proper:

• Ventilation

• Gas monitoring

• Personal protective equipment

• Purging after descaling

Always add acid to water, never the reverse.
