Skimmel-, rust- og kalkfjerner – saltbaseret sur rengøringsspray 500ml Sanitify

pH 0.4 is a strong acid, but the key distinction is that Sanitify uses organic salts (naturally-derived acids) rather than mineral acids like hydrochloric (muriatic) acid or sulphuric acid. This makes it significantly safer to handle — it does not produce fumes at room temperature, does not burn on brief skin contact (though gloves are recommended for extended use), and does not corrode metal fittings or damage most ceramic and glass surfaces that mineral acids would attack. It is a targeted descaling agent, not a corrosive industrial chemical.

Yes. The Sanitify organisk syrerenser is effective at dissolving the organic matter and mineral deposits that allow black mold (typically Cladosporium or Aspergillus species) to anchor in grout and silicone joints. Spray directly onto affected grout lines, allow 5–10 minutes dwell time for established mold, then rinse. For deeply embedded mold in porous grout, a second application and light brushing may be needed. For best long-term results, follow up with the Sanitify Probiotic Cleaner, which colonises the freshly cleaned surface with beneficial bacteria and makes it hostile to mold re-establishment.

Yes — this is one of the most popular uses. Dilute the concentrate 1:10 with water and run through your kettle or coffee machine as you would a commercial descaling solution. For washing machines, add 100ml to the detergent drawer and run an empty hot cycle. The organic acid formula dissolves calcium carbonate (limescale) safely and effectively on all internal surfaces including metal heating elements, plastic reservoirs, and rubber seals. Always run one additional plain water cycle after descaling to rinse the appliance thoroughly before use.

Avoid using on natural marble and polished limestone — acids will etch and dull the polished finish permanently. Do not use on untreated aluminium (it can cause pitting with prolonged contact), painted surfaces (may affect paint adhesion), or any surface with metal that shows visible rust and you want to preserve the metal intact (the acid will continue to react with iron). For these surfaces, use the Sanitify Probiotic Universal Cleaner instead. For everything else — ceramic, porcelain, glass, stainless steel, chrome, plastic, PVC — the organic acid formula is safe.

Most commercial limescale removers contain either hydrochloric acid (which produces harsh fumes and corrodes metal) or citric acid (which is gentler but less effective on heavy deposits). The Sanitify organisk syrerenser uses a proprietary organic salt blend that combines the effectiveness of mineral acids with the safety profile closer to citric acid — no fumes, no corrosive splash risk, biodegradable breakdown. It also contains no phosphates, which are a common environmental concern in conventional descalers that enter waterways and cause algae blooms.
