Faren Descalers and Limescale Removers — Cistern Treatment, Shower Descaler and Mould Removal for UK Plumbers
Why Plumbers Need the Right Descaling and Cleaning Chemicals
Limescale, rust and mould are among the most common maintenance issues UK plumbers deal with on every job. Hard water areas — which cover most of England — accelerate scale build-up inside cisterns, showerheads, pipework and appliances. Using the correct chemical treatment saves time on site and prevents premature replacement of fittings.
Faren is a specialist Italian manufacturer producing professional-grade maintenance chemicals, widely used by UK trade plumbers and property maintenance contractors. Their descaler and cleaning range is designed for fast, effective treatment without damaging seals, gaskets or plastic components.
APM Electricals stocks a core range of Faren descaling and maintenance products available for click-and-collect or next-day delivery.

The F200 is Faren's dedicated cistern descaler, formulated specifically for toilet cisterns and continuous slow-release limescale prevention. It treats hard water deposits inside the cistern, keeping the flush valve, ball valve and internal mechanisms free from scale build-up.

- Safe on rubber seals, plastic cistern components and ceramic
- Suitable for all standard flush cisterns including close-coupled and back-to-wall
- Reduces frequency of flush valve and fill valve replacements in hard water areas
- Fast-acting acid-based formula that breaks down calcium and magnesium deposits
Trade use: Pour directly into the cistern and allow to work before flushing. Ideal for rental property maintenance, hotel room servicing and school/office bathroom maintenance contracts.

FAREN Citrus Limescale Remover 750ml

- 750ml spray bottle — ready to use, no dilution required
- Citric-acid based formula — biodegradable and lower-odour than hydrochloric acid alternatives
- Effective on taps, showerheads, basin surrounds, tile grout and bath panels
- Safe on chrome and brushed nickel fittings
- Quick contact time — spray, leave 5–10 minutes, rinse
Trade use: Ideal for end-of-tenancy cleans, new bathroom commissioning, and routine maintenance of bathroom suites in rental or commercial properties. Works well in combination with the F200 cistern treatment for a complete hard water maintenance package.
Faren Easy Descaler 500ml
Faren Easy Descaler 500ml
Price: £8.99 inc VAT
Faren Easy Descaler is a multi-purpose descaling fluid suitable for showerheads, electric showers, immersion heater elements, steam irons and domestic appliances. It's the plumber's go-to when commissioning or servicing hot water systems and shower installations in hard water areas.
- 500ml — concentrated solution, dilute as required per application
- Safe on heating elements, shower bodies, flow restrictors and plastic components
- Effective on calcium and limescale deposits inside showerheads and flow-restrictors
- Can be used to soak showerheads or as a flush through electric shower heads
- Suitable for use in customer-facing after-care advice
Trade use: Electricians and plumbers fitting new electric showers or replacing shower heads should supply a bottle to the customer as part of a hard-water maintenance pack. Particularly relevant in London, Essex, Kent and the South East where water hardness exceeds 300mg/l CaCO₃.
Faren MUFFYXID Mould Removal Spray 500ml
Faren MUFFYXID Mould Removal Spray 500ml
Price: £13.39 inc VAT
MUFFYXID is Faren's professional mould and mildew removal spray, designed for bathrooms, wet rooms, silicone joints, grout lines and damp-affected surfaces. Where descalers address mineral deposits, MUFFYXID addresses the biological growth that accompanies poor ventilation and condensation — a common companion problem in UK bathrooms.
- 500ml spray bottle — concentrated biocidal formula
- Eliminates mould, mildew, algae, fungus and moss on contact
- Effective on grout, silicone, ceramic tile, UPVC window frames and masonry
- Delays re-growth — the formula leaves a residual barrier on treated surfaces
- Fast-acting: visible results within 5–10 minutes on black mould
- Suitable for bathrooms, shower enclosures, wet rooms and utility areas
Trade use: Essential add-on product for bathroom refits, extractor fan installations and damp investigation jobs. Plumbers and decorators fitting new bathroom suites should treat existing mould before tiling and sealing to prevent regrowth beneath new silicone. Pairs well with Knightsbridge or Screwfix extractor fans to address the root cause.

Hard Water Areas in the UK — Where Descaling Matters Most
If you work in London, the South East, East Anglia, the East Midlands or the Yorkshire plains, you're in a hard water zone. Water hardness above 200mg/l CaCO₃ causes visible limescale within weeks on unprotected fittings. In London boroughs, hardness regularly exceeds 300mg/l.
For landlords and letting agents managing multiple properties, a van-stock supply of Faren F200, citrus remover and Easy Descaler provides a cost-effective first-response to limescale complaints before calling out a plumber.
