What's in the Cleaning & Maintenance Collection
The range covers three distinct areas of espresso machine care. Each addresses a different type of buildup and requires different products.
Cleaning Products
Chemical cleaning products for removing the organic and mineral residues that accumulate inside espresso machines and grinders with daily use. The range is built around Cafetto — a specialist coffee equipment cleaning brand whose products are used as the professional standard in specialty cafés worldwide and are certified organic across the core range. Products in this category include Cafetto EVO espresso machine cleaner for backflushing, Cafetto Organic Descaler in 250ml and 1 litre sizes, Cafetto MFC Green milk frother cleaner, Cafetto grinder cleaning tablets in home and trade sizes, and backflushing blank discs from Rhino Coffee Gear and Coffee Hit. See the full Cleaning Products collection for individual product details and a recommended home maintenance schedule.
Towels & Brushes
Physical cleaning tools for the daily surface-level maintenance tasks that chemical products don't cover: wiping steam wands, brushing group heads, sweeping grinder dosing areas and keeping the bar clean between sessions. All products in this category are from Rhino Coffee Gear. The range includes the Barista Cloth Set (the most-reviewed product in the collection), the Group Head Brush and spare brush heads, the Grinder and Bench Tidy Brush and spare bristles, and the Steam Wand and Milk Frother Brush Set. Spare burr brass brushes for deep-clean grinder disassembly are also stocked. See the full Towels & Brushes collection for guidance on which brush does what.
Water Filters
Inline water filtration systems for espresso machines, addressing water quality at the source rather than managing its consequences. BWT's Bestmax and Bestmin filter range — used in specialty cafés and Michelin-starred restaurants worldwide — reduces chlorine, sediment and scale-forming minerals while actively balancing the mineral content that coffee extraction benefits from. The range includes filter cartridges in multiple sizes, the Besthead FLEX filter head, a complete plumb-in kit with Bestmax filtration included, a water meter for tracking cartridge usage, and a water test kit for measuring supply hardness before specifying a filter. See the full Water Filters collection for cartridge selection guidance and UK regional water hardness context.
A Complete Home Espresso Maintenance Routine
Most espresso machine problems — bitter extraction, inconsistent shots, machine faults — are the direct result of skipped maintenance rather than equipment failure. The following routine covers every task for a home machine used daily, using products stocked in this collection.
- After every session: Purge the steam wand, wipe with a damp barista cloth. Run a water-only blank backflush to clear loose grounds from the group head. Brush the group head gasket and shower screen.
- Weekly: Backflush with Cafetto EVO using the blank disc. Rinse the portafilter basket and shower screen in hot water. Clean the steam wand tip with the brush set.
- Monthly: Soak the portafilter basket and shower screen in a Cafetto EVO solution. Run Cafetto grinder tablets through the grinder. Run a MFC Green cycle through any automatic milk frother system.
- Every 2–3 months: Descale using Cafetto Organic Descaler, following your machine's descaling programme. Adjust frequency based on local water hardness — harder water requires more frequent descaling. Check and replace BWT filter cartridge if approaching rated capacity.
- Annually: Inspect and replace the group head gasket and shower screen if worn. Replace BWT filter cartridge regardless of volume if not already done. Deep-clean grinder burrs using Cafetto tablets followed by a burr brush during disassembly.
Frequently Asked Questions
What cleaning products do I actually need for a home espresso machine?
The non-negotiables are: a backflushing detergent (Cafetto EVO), a blank disc to run it with, and a descaler (Cafetto Organic Descaler). These three cover the two most critical maintenance tasks — removing coffee oil buildup from the group head and removing mineral scale from the boiler. A group head brush for daily use and a barista cloth set for steam wand wiping round out the essential kit. Grinder cleaning tablets are important if you have a burr grinder and use it daily — they're often overlooked but make a noticeable difference to shot quality over time. A milk frother cleaner is required if your machine has an integrated or automatic milk system. A BWT water filter is strongly advisable in hard water areas (most of England) and will extend the intervals between descaling significantly.
How do I know if my espresso machine needs cleaning?
The most common signs are: shots that taste increasingly bitter or harsh despite no change in grind or dose; reduced or uneven flow from the group head; a slower or noisier steam wand; visible brown residue on the shower screen or inside the portafilter basket; and a machine that takes longer than usual to reach temperature. Any of these suggests overdue backflushing or descaling. A more subtle sign is shots that have gradually become less consistent over weeks — often the result of oil buildup in the group head that isn't visually obvious but is affecting extraction. If you can't remember the last time you cleaned your machine, that's the answer.
Can I use supermarket descaler in my espresso machine?
Not safely. Most household descalers — including those sold for kettles and dishwashers — contain sulphamic acid, citric acid at aggressive concentrations, or hydrochloric acid, which can corrode the brass, copper and aluminium components inside espresso machine boilers and water lines. Cafetto's organic descaler is specifically formulated for espresso machines: effective against limescale, food-contact safe, and free from compounds that damage internal metals. Always use a descaler specified for espresso equipment, and follow your machine manufacturer's descaling programme — some machines require a specific cycle sequence for the descaler to reach all internal pathways.
How does water filtration fit into a cleaning routine?
Water filtration and chemical cleaning complement each other — they don't replace each other. A BWT inline filter reduces the rate at which scale forms inside the machine by reducing the hardness minerals entering the boiler. In hard water areas this means descaling much less frequently — many home users with a properly specified BWT filter go 12 months or more between descales rather than every 6–8 weeks without filtration. However, a filter does not eliminate scale entirely (some minerals are retained by design for extraction quality), and it does nothing for coffee oil buildup in the group head, which requires regular backflushing regardless of water quality. The two routines address different problems: filtration manages mineral scale at source; backflushing manages organic residue from the coffee itself.
Do I need to clean my grinder as well as my espresso machine?
Yes — and most home baristas don't do it often enough. Coffee oils coat the burrs and burr carrier with every grind, and those oils go rancid within days at room temperature. Stale oil residue in the grind path contributes off-flavours to every shot it contaminates — a slow, cumulative degradation that's easy to miss because it happens gradually. Running Cafetto grinder cleaning tablets through the grinder every 4–8 weeks (depending on use frequency) removes this buildup without disassembly. If you're switching between very different coffees — different origins or roast levels — running a small dose of tablets between them speeds up the transition and prevents flavour carry-over.
