Cleaning innovation for soldering systems at productronica 2025

With the new, pH-alkaline Etimol SEM 14 RAA, Emil Otto presents a state-of-the-art cleaner that has been specially developed for the cleaning requirements of soldering systems in electronics production.

October 2, 2025

The water-based product will replace the Etimol SEM 11 RAA cleaner and combines particularly strong foaming with intensive cleaning power.

Etimol SEM 14 RAA reliably removes burnt-on flux residues and condensates. The mild and non-corrosive odor in particular enables gentle use for cleaning personnel.

"The new Etimol SEM 14 RAA is formulated with special organic solvents and is ideal for use in reflow, wave, selective and vapor phase soldering systems, where stubborn residues regularly occur and can have a significant impact on process reliability. The cleaner was therefore developed with highly active additives to achieve extremely high effectiveness. Highly corrosive cleaners are often used in soldering systems due to the stubborn soiling. This leads to employees complaining of nausea and headaches after cleaning the equipment. Aluminum parts can also be severely attacked. The Etimol SEM 14 RAA prevents this, with the same cleaning performance."
Markus Geßner, Head of Marketing and Sales at Emil Otto GmbH

Etimol SEM 14 RAA effectively dissolves soiling

The area of application includes both the regular maintenance of soldering systems and thorough cleaning after intensive production cycles. Thanks to the stable foam formation, Etimol SEM 14 RAA adheres optimally to the surfaces, dissolves soiling effectively and can then be removed without leaving any residue. The cleaner works reliably even when the systems are still warm and no deposits remain, so that the systems are ready for use again immediately after cleaning.

The formulation of the water-based Etimol cleaner has been specially developed to ensure environmental compatibility and a high flash point, among other things. The new product therefore offers numerous advantages for users. Etimol SEM 14 RAA is non-flammable, free from corrosive chemicals and halogen-free, guaranteeing a high level of occupational safety. At the same time, the cleaner has a low odor and can be used directly as a ready-to-use foam without time-consuming dosing. This saves time, reduces incorrect applications and increases efficiency in the maintenance process.
