If you live in London, Cambridge, or anywhere in southern and eastern England, your bathroom and kitchen have limescale problems no general spray will fix. The three products below are ranked by intensity. From the budget Cillit Bang you can use weekly, through the popular Viakal, to HG’s professional strength for severe cases. Each does a different job at a different price point.

Our top picks, in detail

Cillit Bang Limescale & Shine Spray 750ml

4.0 £3.31 on Amazon UK 44.1p per 100ml S&S £3.31

Pros

  • Big 750ml bottle
  • Reliable on moderate limescale
  • Widely available, cheap per 100ml

Cons

  • Weaker than Viakal on glass shower screens
  • Fragrance is strong
  • Not the no-scrub Cilit Bang advertises

Cillit Bang Limescale & Shine is the value pick. At £3.31 per 750ml bottle (the 3-pack at £9.93 works out to that) it’s the cheapest of the three on a per-ml basis by a wide margin, and it handles routine bathroom limescale on glass and chrome without much fuss.

The Cillit formula is less concentrated than Viakal or HG, so on stubborn marks you’ll need to spray, leave for a few minutes, and re-apply. For weekly maintenance on a moderately hard-water bathroom it’s the right tool. For severe deposits, step up.

Viakal Limescale Remover Spray 500ml

5.0 £4.45 on Amazon UK 89p per 100ml

Pros

  • The UK gold standard for limescale removal
  • Visibly works on glass shower screens within minutes
  • Reliable on taps, showerheads, tile grout
  • Makes Mr Muscle's no-scrub claims actually true

Cons

  • Strong acidic formula, ventilate the bathroom
  • Not a daily product. Use targeted, not as a general spray
  • Expensive per 100ml relative to general bathroom sprays

Viakal is the bathroom-cleaning standard for a reason. The formula is engineered specifically for limescale, not as a general bathroom spray, so it works where Cillit Bang and all-in-one sprays fail.

At £4.45 per 500ml bottle (the 2-pack at £8.99 splits to that price) Viakal costs about twice as much per 100ml as Cillit Bang, but you’ll use a fraction of the amount. On glass shower doors, chrome taps, and around tap bases, one application lifts what other products only fade. If you live in an area with a lot of limescale, Viakal is the default answer.

HG Professional Limescale Remover 500ml

4.5 £10.54 on Amazon UK £2.11 per 100ml S&S £10.54

Pros

  • Stronger acid concentration than Viakal
  • Works on the worst kettle and tap limescale
  • Reliable in <5 minute contact time

Cons

  • More expensive per 100ml than Viakal
  • More aggressive, ventilate thoroughly
  • Not needed if Viakal already works for you

HG Professional Limescale Remover is the heavy-duty option. Specialist concentration for the cases where Viakal won’t shift the deposit, typically toilet bowls with calcium build-up below the water line, kettle scale you’ve ignored for too long, or shower heads that have been gummed solid.

Use it sparingly and only where you need it. It’s not a daily product. £10.54 for 500ml feels expensive until you remember you only reach for it three or four times a year, and the alternative is replacing the fixture.

What we’d buy

In a moderately hard-water area (Manchester, Leeds, Bristol), Cillit Bang Limescale & Shine handles weekly bathroom maintenance. It’s the cheapest per ml on the list, and that matters when you’re using it every week.

In a properly hard-water area (London, Cambridge, southern and eastern England), buy Viakal instead. Stronger formula, lifts deposits Cillit Bang only fades, and you’ll use less per application.

Keep HG Professional in the cupboard for the once-or-twice-a-year emergency: kettle scale, toilet bowl deposits below the water line, gummed-up shower heads. Don’t use it daily.

How we pick value

Limescale removers split between 500ml specialist bottles and 750ml all-rounders, so cost per 100ml is the only fair way to compare them. The formula concentration matters too, Viakal and HG go further per squirt than Cillit Bang, but that’s why this guide ranks by the right job rather than pure price.

Prices are re-checked regularly. Nothing on this list is paid placement.

How often do you update these picks?

Whenever Amazon UK pricing shifts materially, or when a product we’d previously recommended changes formula. Each product page shows the last-checked price date below the comparison table.

Can I trust the cost-per-use number?

It’s computed live from the price and pack size we last checked, pack price ÷ pack count, or × 100 ÷ ml for liquids. If you spot a number that looks wrong, the source data on the product page is what matters; tell us and we’ll re-check.
