How to clean cloudy glasses

How can I remove hard water film from cloudy glasses?

There is nothing more annoying than reaching into your cupboard for a “clean” glass… and it looks dull, cloudy and just not fresh at all.

But don’t worry this is usually down to hard water build-up, and the good news is it’s really easy to fix with a few simple bits you probably already have at home. Let’s get that sparkle back! ✨

1. The White Vinegar Soak (My Go-To Method)

If your glasses have that milky haze, this is the first thing I always do.

• Fill your sink with warm water and a good glug of white vinegar

• Pop your glasses in and leave them to soak for at least an hour

• Use a non-scratch sponge to gently remove any stubborn marks

• Rinse and dry straight away with a lint-free glass cloth

Lynsey Tip: Drying is just as important as cleaning if you leave them to air dry, those water marks will come straight back.

2. Stop It Coming Back (Dishwasher Fixes)

If this keeps happening, your dishwasher could be the culprit.

• Make sure you’re topping up dishwasher salt this softens the water

• Always use rinse aid so water runs off properly

• Run a dishwasher cleaner once a month to remove hidden limescale

✦ Rinse Aid 
✦ Dishwasher Cleaner

This alone can make a massive difference to how your glasses come out.

3. The Denture Tablet Trick (So Good!)

For those awkward glasses and vases you can’t get your hand into:

• Drop in a denture tablet

• Fill with warm water

• Let it fizz away and break down the residue

• Use a long-handled brush if needed

Honestly, this works so well and takes zero effort.

4. Etching vs Limescale (Know the Difference)

Before you go scrubbing away, check what you’re dealing with:

• Rub a little white vinegar onto the cloudy area

• If it disappears when wet but comes back when dry it’s limescale (fixable ✔️)

• If nothing changes it’s likely etching (permanent ❌)

Etching happens from high heat and too much detergent in the dishwasher, so for your best glasses, I’d always recommend gentle hand washing.

Lynsey’s Sparkle Tip ✨

Ditch the fluffy tea towels! They leave tiny fibres behind and ruin that clean finish.

Always use a proper glass cloth it’s the secret to that streak-free, just-out-of-the-box shine.

Final Thought

This is one of those quick wins that makes such a difference.

A simple soak, a few tweaks to your dishwasher routine, and your glasses will be back to crystal clear in no time no more cloudy cupboards!
