Cafetto Renew Espresso Machine Descaler

A safe and effective powder descaler for removing hard water scale from espresso machine boilers, coffee and milk delivery lines. Can also be used to descale bottles and kettles. Contains a synergistic blend of organic acids that give outstanding scale removal.

The ingredients and formulation of the products that are NSF certified are safe, leave no harmful residues and do not cause corrosion within the coffee machine. Safe to use on aluminium, brass and stainless steel.

All ingredients are all rapidly biodegradable meeting international standards.

Each 25g sachet makes up one litre of descaling solution.

Single-Dose Descaling, No Measuring Required
The Cafetto Renew Espresso Machine Descaler is the single-sachet solution for home baristas who descale occasionally and want a straightforward, no-fuss process. Each 25g sachet dissolves into one litre of descaling solution — exactly the volume most domestic espresso machine manufacturers specify for a standard descaling cycle — so there's no measuring, no leftover powder to store, and no guesswork about concentration. Follow your machine manufacturer's instructions for the descaling cycle, then rinse thoroughly with fresh water at least twice before returning the machine to service.

NSF Certified, Organic Acid Formula
Cafetto Renew uses a synergistic blend of organic acids formulated to remove hard water scale from espresso machine boilers, coffee delivery lines, milk delivery lines, and connected components like kettles or water tanks. The formulation is NSF certified — independently verified to leave no harmful residues and to not cause corrosion within coffee equipment. Safe to use on aluminium, brass, and stainless steel, which covers the full range of internal materials in most domestic espresso machines. All ingredients meet international biodegradability standards, making Renew one of the more environmentally considerate descaling options in the category.

Where Renew Fits in the Cafetto Descaling Range
Renew is the per-sachet entry point in Cafetto's descaler lineup — ideal for infrequent descaling or for keeping one or two sachets on hand as part of a general maintenance kit. For higher-volume descaling or for those who prefer a liquid format, the Cafetto Liquid Organic Descaler (1L, 8 doses with dispensing chamber) and the Cafetto Restore powder descaler (1kg jar, 40 litres) are both available at Coffee Addicts and use a similar organic acid approach. Note that descaling addresses hard water scale — a separate maintenance task from backflushing with Espresso Clean, which removes coffee oils and residue from the group head. Both are part of a complete machine care routine.
