Why this detergent earns its place
Winterhalter F420e is the environmentally-conscious option in the range without giving up cleaning power – an EU Ecolabel-certified, alkaline liquid detergent suitable across all water hardnesses, so it doesn't need matching to local water conditions the way some detergents do. It's built for bistro-style operations dealing with a constant mix of beverage residue alongside slightly dried-on food, coffee and tea residues, the everyday grind of a busy front-of-house wash-up rather than occasional heavy staining.
Its highly concentrated formula removes colouring and tanning agents – the kind of staining tea, coffee and red wine leave behind – without producing any odour, and it also removes lipstick and other grease residues from glass rims. Despite the intensive cleaning power, it's noted as very gentle on glass, which matters given how much glassware runs through a bistro or bar dishwasher daily.
It's suitable for glass, plastic, porcelain, stainless steel, cutlery and utensils, but there are two clear exclusions worth knowing before you use it: it's not suitable for drinking glasses with decor, or for aluminium. It comes as an unperfumed, grey liquid in a 9.9 litre pack. As a corrosive concentrate it's supplied under hazardous goods delivery rules and arrives non-returnable, so check those two exclusions against your glassware before ordering.
COSHH: six habits of safe chemical use
Control of Substances Hazardous to Health — the routine every commercial kitchen and cleaning cupboard is expected to run.
SDS
Read the label and the manufacturer’s safety data sheet — the pictograms tell you what you are holding.
Who could be harmed, and how badly? Judge likelihood against severity before anyone opens the cap.
Eliminate or substitute first, engineer and organise next — PPE is the last line, never the first.
Keep the controls working: check ventilation, dosing equipment and storage stay as they should be.
Everyone who uses it knows the hazards, the correct dilution and the PPE — before the first shift, not after.
Products and processes change. Reassess when they do, and keep the record that proves it.
