Puligen by Interchem Italia is a strongly acidic professional descaling detergent in a 1-litre bottle, designed to rapidly remove limescale, grease, rust stains, urine scale and mortar or plaster efflorescence from acid-resistant surfaces. With pH 1 and a formula free from hydrochloric acid, it is diluted at 1 to 10 % in water and serves professional kitchens, hotels, facility management and cleaning companies in Switzerland through LAPA.
What Is Puligen
Puligen is a fast-acting acid descaler and degreaser for professional use. Unlike household anti-limescale products, it works at pH 1 and combines descaling and degreasing power in a single product: it dissolves calcium deposits while removing greasy films, restoring shine to metal surfaces. Its formula contains acids below 5 % and non-ionic surfactants (Reg. EC 648/2004) and is deliberately free from hydrochloric acid, which means fewer aggressive fumes and a lower risk of corrosion halos on stainless steel compared with traditional hydrochloric descalers.
The Producer: Interchem Italia
Puligen is produced by Interchem Italia, a professional cleaning chemistry company based in Vigonza, in the province of Padua (Veneto, Italy), and a member of AFIDAMP, the Italian association of professional cleaning manufacturers. Interchem Italia develops chemical lines dedicated to the HORECA channel, communities and cleaning services. On the Swiss market the Puligen line is available through the LAPA professional non-food catalogue.

How to Use It
For routine maintenance, dilute Puligen at 1 to 10 % in water depending on the level of scaling: 1-3 % for frequent cleaning of sinks and tiles, 5-10 % for periodic deep descaling of showers and sanitary ware. Apply with a sponge while wearing protective gloves, leave to act briefly, then rinse thoroughly with clean water. On stubborn deposits such as urine scale or mortar residues the product can be used undiluted, always followed by abundant rinsing. Never mix with chlorine-based products.
Where to Use It
Puligen is suitable for professional kitchens (stainless steel sinks, pots, aluminium cutlery), ceramic tiles, glass, showers and sanitary fixtures, and for removing rust stains, efflorescence and mortar or plaster residues at the end of building works. Do not use on marble, natural stone or acid-sensitive surfaces: test first on a hidden spot.
Common Mistakes to Avoid
- Using it on marble or natural stone: the acid etches calcareous materials permanently — use a neutral detergent instead
- Letting it dry on the surface: always rinse before the solution dries, especially on aluminium
- Working without gloves: the product is corrosive (GHS05) — protective gloves are mandatory
