Whether you keep them lined up empty on a shelf or filled with fresh flowers, leaves, twigs or anything else that takes your fancy, glass decor can provide eye-catching decorative elements in any room. Condition is key to visual appeal, and cloudiness – a common problem in old glass – can mar its appeal. So what is the best way to treat and prevent it? We explain all…

You Will Need –
A plastic washing-up bowl
Lukewarm water
Washing-up detergent
Cotton wool pads
A bottle brush or artist’s bristle brush
Soft sponge
Paper kitchen towel
Microfibre clot
Vinegar
Denture tablet

  • Using a plastic bowl rather than the sink (in case you knock the vase and chip it), fill it with lukewarm water and a drop of detergent per litre. Ensure the water isn’t too hot: glass is extremely susceptible to sudden changes in temperature and can shatter or crack if exposed to extremely hot (or cold) water. Avoid using the dishwasher to wash old or fragile glass – the heat and abrasive detergents will damage the surface and turn glass cloudy.
  • Dip one object at a time into the lukewarm water, then wipe the surface gently with cotton wool pads to remove any grime or dirt, using a long-handled artist’s brush or a bottle brush for narrow areas. If the vase is gilded or enamelled, use a soft sponge, minimal water, and avoid rubbing in case any of the beautiful decoration wears away.
  • Rinse thoroughly in a bowl of clean water or, if you prefer, use damp cotton wool pads.
  • Blot dry using a paper kitchen towel or microfibre cloth and, provided the vase is reasonably stable, leave it upside down to dry.
  • Hard water contains mineral deposits that can calcify on the surface when left in contact with the glass for long periods and is the most common cause of cloudiness. To remove, try filling the vase with vinegar and leaving for several hours or even overnight, then wash, rinse and dry. If stains persist and the glass is robust, you can try soaking with a denture tablet. To avoid this type of damage, don’t leave vases filled with water for long periods – clean them thoroughly after use and allow them to rest before refilling.
