Bulk Descaling for High-Frequency or Multi-Machine Use
The Cafetto Renew Espresso Machine Descaler in the 2kg jar is the high-volume format of the same NSF-certified organic acid powder available in single 25g sachets. At 25g per litre of descaling solution, the 2kg jar yields 80 litres of solution — equivalent to 80 full descaling cycles — making it the practical choice for cafés, offices, and multi-machine environments where descaling happens frequently and buying sachets individually is neither efficient nor economical. The same safe, effective formula as the sachet format: a synergistic blend of organic acids that removes hard water scale from espresso machine boilers, coffee and milk delivery lines, kettles, urns, and bain-maries, with no harmful residues and no corrosion risk.

NSF Certified — Safe Across All Machine Metals
Cafetto Renew is NSF certified: independently tested and evaluated to NSF's toxicological and corrosivity standards, confirming the formulation is safe in coffee equipment and leaves no residue that affects taste or machine integrity. The powder is safe to use on aluminium, brass, and stainless steel — covering the full range of internal materials in commercial and domestic espresso machines and hot water equipment. All ingredients are rapidly biodegradable and meet international environmental standards. Dilution is 25g per litre of warm water; dissolve fully before pouring into the machine's water tank or applying to the equipment per the manufacturer's descaling instructions. Always rinse at least twice with fresh water after descaling and before returning the machine to service.

Where the 2kg Renew Fits in the Cafetto Descaler Range
Renew is Cafetto's general-purpose NSF-certified organic acid descaler — distinct from the Cafetto Restore (which carries the additional OMRI and BFA organic certifications for organic coffee environments) and from the Cafetto LOD® Black (a heavy-duty double-action descaler for severe scale buildup, not suitable for aluminium). For routine scale maintenance across espresso machines, boilers, kettles, and coffee brewers, Renew is the appropriate choice. For single-use descaling at home, the Cafetto Renew sachet (25g, $2.50) is available separately. Pairs naturally with Cafetto Espresso Clean® or EVO® for a complete machine maintenance routine that addresses both scale and coffee oil buildup.
