White Vinegar 12% 1 Litre and 5 Litre. White vinegar at 12% acidity is much stronger than our standard household white vinegar, which is 5%. 

Because it’s more concentrated, it works especially well for:

• Heavy limescale and hard-water build up
• Patio and outdoor cleaning
• Mould and mildew removal
• Degreasing
• Cleaning toilets and drains
• Weed control in cracks and paths
  
  Of course the vinegar can be diluted with water to reduce strength making it more economical than it already is.

What not to clean with vinegar

Avoid using it on:

• Natural stone (granite, marble) — it can etch the surface
• Hardwood floors (unless specifically recommended)
• Electronics screens
• Rubber seals (over time, it can degrade them)
  
  
• Safety notes

    Wear gloves if using it undiluted. 

    Use ventilation in enclosed spaces. 

    Never mix vinegar with bleach — it can release toxic chlorine gas. 

    Keep away from natural stone, grout sealants, and some metals.
