Acidic cleaners

Acidic cleaners remove mineral deposits such as limescale, rust, and cement and concrete film, which alkaline or neutral cleaners are largely unable to tackle. Eco-Nova offers Oxinova, Novascal and Meganova for this purpose. They are labelled as corrosive – we can advise you on selection, dosage and safety precautions.

Problem and Solution

The challenge

Lime, rust and cement residues adhere firmly and build up with every layer. Acids that are too strong or unsuitable can corrode metals, wash out joints or etch surfaces. Mechanical removal is time-consuming and often causes further damage to the material.

Our solution

We select the cleaner based on the type of deposit and the material, and adjust the dosage accordingly. This allows you to remove deposits using as little acid as necessary. Our acidic cleaners are labelled as corrosive; protective equipment and instructions for use can be found in the safety data sheet. On request, we can demonstrate how to use them on site.

Typical areas of application

  • Descaling of systems and pipework
  • Removing rust from metal surfaces
  • Cement and concrete residue on machinery
  • Mineral-based flooring and tiles
  • Boilers and mixers

FAQ

Frequently Asked Questions

When do I need an acidic cleaner?
For mineral deposits such as limescale, rust, cement or concrete. Alkaline cleaners are more effective at removing oil, grease and other organic dirt.
Do acidic cleaners corrode metal?
This depends on the acid, concentration, contact time and metal. We recommend carrying out a preliminary test and will tailor the dosage and contact time to your material.
What protective equipment do I need?
Eco-Nova’s acidic cleaners are classified as corrosive. The necessary protective equipment – usually protective gloves and eye protection – is listed in Section 8 of the safety data sheet.
Can I try out the cleaning products beforehand?
Yes. We provide free samples and, on request, demonstrate how to use them on site.

Acidic cleaners for mineral deposits

Acidic cleaners are the first choice for removing limescale, rust or cement residues. They effectively dissolve mineral deposits and are used in many industrial areas - from the construction industry to metalworking.

Typical properties & areas of application

Due to their low pH value, they are particularly effective against inorganic residues. Typical areas of application are pipework, tiles or metal surfaces.

Advantages of Eco-Nova cleaners

Our acidic cleaners are formulated to tackle different types of deposits, so you do not need to use more than is necessary. Like many strongly acidic cleaners, they are classified as corrosive and must be used with appropriate protective equipment – please refer to the safety data sheet for further guidance.

Application examples & advice

From cleaning floors and machines to metal descaling - Eco-Nova offers suitable solutions. We are also happy to provide you with samples.
