  • Free from Chlorine Bleaches, Formaldehyde, Phosphoric Acid, Hydrochloric Acid, Fragrances, and contains low VOC’s
  • Safe in septic tanks if used as directed
  • Readily biodegradable
  • Phosphate and phosphonate-free

Use regularly to prevent limescale build-up.

Instructions for Use 

Spray onto the surface, leave for a few moments, wipe with a damp cloth to remove stubborn deposits, and rinse well. Polish surfaces using a dry cloth. 

Avoid use on acid-sensitive surfaces such as aluminium, gold, silver or copper, damaged or hot surfaces. DO NOT USE on natural stone such as marble. 

As a housekeeping product, the formula can also be poured directly into kettles in hotel rooms. Boil full kettle, add 100/150ml of Foaming Descaler (depending on limescale build up) and leave for 20 mins, rinse until no more foam is present. If you're looking for a heavy duty limescale remover for commercial kitchens, please see our Combi Scale Descaler.

Areas of Use

  • Sinks
  • Taps
  • Baths & Showers
  • Shower Screens
  • Shower Heads
  • Kettles (Hotel rooms housekeeping only)


If you're looking for a housekeeping limescale remover for hotel rooms and small bathrooms, this Foaming Descaler is ideal. However if you need a more heavy duty limescale remover for commercial kitchen appliances, check out our Combi Scale Descaler.



Frequently asked questions

What is limescale?

Limescale is a hard white substance mainly made up of calcium and magnesium which is left behind when hard water evaporates. “Hard water” is produced when water travels through chalky limestone lands and picks up lime along the way. Geologically, there is a lot of limestone in the south
of the UK, especially around the North and South Downs. But, as water is transported all over the country, it can travel to places that historically do
not have hard water, so it’s important to be able to identify limescale and treat it before it becomes a problem.

How do I know if I’m in a “hard water” area?

Around 60% of the UK is classed as having hard or very hard water, with many areas exhibiting over
200mg of calcium carbonate per litre from a “soft water” baseline of 60mg per litre. If you check out our map of the UK above, you can see if your area has hard water.

How does limescale appear?

There are two primary ways limescale forms:

1. EVAPORATION: Water evaporates leaving the scale-forming minerals behind on surfaces, these then bond to the surfaces and stay there, leaving
behind hard white deposits. This is often found on taps, plugholes, showerheads and glass.

2. HEAT: When water is heated, the minerals within the water will rapidly begin to form scale (hard white pieces which float around), which is why limescale commonly builds up quickly in hot appliances like kettles and irons.

How do I know if I have limescale?

The most obvious signs of limescale are:

  • What limescale looks like on taps: hard white deposits around taps, plugholes and sinks.
  • What limescale looks like on showers: shower pressure might be down, and there will be build-up around the nozzles on the showerhead. The shower glass may also become cloudy.
  • What limescale looks like in a kettle: you might get bits of limescale in tea and see them floating in the kettle, particularly around the heating mechanism which may cause it to stop working as efficiently.
  • What limescale looks like in an iron: it might be struggling to heat up and leave white flakes on clothes.
  • What limescale looks like in a coffee machine: the
    steam nozzle may become clogged and the machine may stop working properly
  • What limescale looks like in a washing machine: clothes coming out of the washing machine smell bad, and the actual drum may also begin to smell.
  • What limescale looks like in a toilet: faecal particles stick to limescale in the toilet bowl, causing the limescale to look like a brown stain underneath the waterline.

 If you’re looking to remove limescale on vertical surfaces or in bathrooms/washrooms, use our Foaming Descaler. In the toilet, use our Daily Use Toilet Cleaner. However, if you’re looking for a more heavy duty limescale remover to descale any appliances, use our Combi-Scale Descaler.

Why is limescale bad?

Limescale is not dangerous to ingest if you’re only just beginning to notice it in your cup of tea. But, over time limescale build-up can become a breeding ground for bacteria and has been associated with legionaries disease, putting your staff and customers at risk. It can also ruin treasured appliances. The heating elements in these systems quickly accumulate limescale, leading to hotspots and eventual failure as the limescale corrodes the heating mechanism. Besides causing damage, limescale diminishes efficiency over time, resulting in increased energy consumption. So, it’s important to tackle a limescale problem as soon as you notice it.

How does Foaming Descaler work?

Solid limescale has a high pH, it’s alkaline – you need to lower the pH to neutralise the limescale using an acid. The acid level brings the overall pH of the limescale down and when limescale is at a lower pH it’s more soluble (it becomes liquid again). So, the
acid in the Foaming Descaler dissolves the limescale, making the limescale liquid again and so it can wash down the drain. Our Foaming Descaler has a pH of 2.

Why is it better to use eco-friendly limescale?

A lot of conventional commercial limescale removers use toxic acids (like hydrochloric acid or phosphoric acid), which are not only dangerous for us but also for aquatic life. Our Foaming Descaler uses citric and formic acid (both plant-derived), and responsibly sourced plant-based cleaning agents.

A lot of conventional limescale removers also use fragrance in their formulas – there is no purpose to these other than a “pleasant citrus/berry/basil scent”. At Delphis Eco, we try to minimise harm to both the user and the environment and only use fragrance where absolutely necessary (like the toilet – and you know why). But fragrances like limonene or benzyl salicylate make formulations less biodegradable and often cause irritation and allergens in the user. So for us, adding fragrance to every single product is not a great idea, especially when it isn’t really needed. And trust us, once you start using products WITHOUT fragrances, you’ll really notice when you visit a business that does, it’ll knock you over (you’ll wonder why you ever used fragranced products in the first place). So, our product is safer for you and your staff to use, safer for your guests and customers, and safer for the planet once it goes down the drain.

Why is it better to have a foaming limescale application?

At Delphis Eco, we love the finer details, and why we choose to “foam or not to foam” might not have been something you’ve considered. When it comes to product performance and user safety, we always ensure we’re using the best possible applicator and foam has a load of benefits when it comes to removing limescale. Firstly, a foaming trigger head means you can be more precise and targeted when treating the limescale, so you won’t misfire on more sensitive materials. The foam also
means there are fewer chemicals in the air, and so reduces the chances of inhaling the formulation. Plus, our Foaming Descaler formulation was developed to cling to surfaces once it’s sprayed on – this increases the contact time to treat the limescale problem more effectively (basically means it won’t quickly start running down bathroom tiles).
