Scale and Rust

71 products

Scale and rust products are used to remove limescale, lime and cement residues and rust stains from floors, hard surfaces, metals and plant, or to convert rust into a stable layer that can be painted over.

Types in the collection

  • Acid descalers: remove limescale and lime and cement residues, including on terracotta and porcelain stoneware floors.
  • Concentrated industrial descalers: to be diluted for cleaning surfaces and plant.
  • Rust converters: stop and transform rust on metal before painting.
  • Deoxidisers: remove rust stains from metals and hard surfaces.

How to choose

First of all the substrate matters: acids attack marble and calcareous stones, so they should be tested first on a hidden spot. Then the nature of the dirt matters: limescale and cement require a descaler, rust a converter or a deoxidiser. Always wear gloves and follow the dilutions given in the technical data sheet.

The catalogue includes products by Chemical Roadmaster, Faren, Firma Chimica and NPT Sigill. AMES works by quotation: tell us what you need to clean and we will recommend the suitable product.

Frequently asked questions: Scale and Rust
Which descaler should I use for limescale?

For limescale, use acid descalers, which dissolve limescale deposits and lime and cement residues, including on ceramic and terracotta. The collection includes, for example, the Chemical Roadmaster Mogol Ceramic descaler for lime and cement and the Cal-Cleaner acid anti-limescale descaler for WC cisterns. Always wear gloves and glasses and read the label before applying the product.

How do I remove rust from iron without replacing the part?

For rust, use converters or rust removers. The converter, such as Faren No Rust, turns rust into a stable layer that can be painted over. Non-acid rust remover gels, such as Chemical Roadmaster DISOXIL GEL R, remove it from the surface. After treatment, dry the metal thoroughly, because moisture reactivates rust.

Can I use a descaler in a coffee machine?

Yes, the collection includes descalers designed for coffee machines, such as Chemical Roadmaster DECAL RC, a liquid acid descaler for food use. Follow the dosage and rinse cycles indicated by the machine manufacturer. After treatment, rinse several times, because product residues must not end up in the drink.

What happens if you mix hydrochloric acid with bleach?

Acids such as hydrochloric acid must never be mixed with bleach or other products, because the reaction can release toxic gases such as chlorine. Use one product at a time, rinse the surface well before changing product and work in a ventilated area. Read the safety data sheet, which lists the incompatibilities and the protective equipment to use.

Which products should I use to descale WC cisterns?

For WC cisterns there are specific acid descalers, such as Chemical Roadmaster Cal-Cleaner. Do not mix it with other detergents and respect the contact times indicated, without leaving the product on for longer than stated. Check on the sheet that the material of the cistern and the drain is compatible with the chosen product.

Which products are there for scale in radiators, boilers and heating systems?

For radiators, coils and boilers the collection offers the Chemical Roadmaster Road Clean descaler, as well as the Decal RA liquid for car and lorry radiators. For flue gas abatement plants there is Road Scrub Super. Always check compatibility with the materials of the system and drain and rinse the circuit according to the manufacturer's instructions.

Who uses descalers and rust-treatment products?

Plumbers, maintenance technicians, body shop workers, craftsmen and professional cleaners use them. They are used to clean building sites after laying mortar and cement, for limescale in bathrooms and plant, to treat rust before painting and for cleaning boat hulls and surfaces.
