Supermarket bag for life alert over little-known risk they pose to your kitchen

Specialists are warning that an ordinary supermarket bag for life could actually inflict serious harm to your kitchen within moments. It sounds hard to believe, but Prestige Granite have disclosed that a reusable plastic carrier could cause havoc in some circumstances.

The specialists explain that when a bag for life becomes moist, its colouring can migrate onto work surfaces, penetrating the material and creating stains that are very hard to remove. They warn the shopping bag has the capacity to generate thousands of pounds worth of destruction in mere seconds, reports Plymouth Live.

Liv Reed from Prestige Granite said: "What many don't realise is that reusable plastic bags often use strong dyes in their design, which can easily transfer when the material becomes damp. On contact with a kitchen surface, especially porous stones such as granite, quartz or marble, the dye particles seep into tiny natural fissures and pores in the material.

"Once absorbed, these pigments bond beneath the surface. If the ink seems impossible to remove, the recommended course of action would be to first try a multi-surface spray.

"If that doesn't work, a cream cleaner such as CIF or The Pink Stuff can be used, followed by acetone if necessary. If this doesn't work, the result is a deep-set mark that doesn't just sit on top of the counter but becomes part of it, often leaving homeowners with no option other than costly professional treatment or replacement.

"It's a silent risk that most households overlook, but simply leaving a wet bag for life on the worktop for a short time could trigger permanent staining, making it one of the most surprising and damaging culprits in the kitchen." Liv has also shared her tips on how to deal with plastic bag stains on your worktop.

• Act fast: As soon as you notice dye transfer, blot the area with a clean, dry cloth to soak up as much of the colour as possible. Avoid rubbing, as this can push the pigment deeper into the surface.
  
  
• Use warm soapy water: Mix mild washing-up liquid with warm water and gently clean the stained patch using a soft sponge or cloth. This is safe for most worktops and can sometimes lift the dye if caught early.
  
  
• Apply a baking soda paste: For stubborn stains, make a paste with baking soda and water. Spread it over the mark, leave for 5–10 minutes, then gently scrub in circular motions before rinsing away.
  
  
• Try a specialist cleaner: If the stain persists, use a non-abrasive stone or surface cleaner designed for granite, quartz, or marble. Always test on a small, hidden area first to avoid further damage.
  
  
• Seek professional help if needed: Deep-set stains may require professional polishing or treatment. In some cases, only a surface specialist can fully restore the worktop’s appearance.
