Why we love it
  • Superior streak-free cleaning power.
  • Economical with high yield ratio.
  • Skin friendly, pH balanced soap.
Main Highlights
  • SMEAR-FREE WINDOW CLEANING - UNGER’s Liquid effortlessly removes dirt and grease with streak-free results, providing superior cleaning power.

  • QUICK, EASY GLIDE FOR SQUEEGEES - Provides enough slip to allow an easy glide over glass with a window squeegee. The right dosage provides enough suds to see where you've washed, and allows you to wipe them off easily and quickly for faster cleaning.
  • ECONOMICAL 1:100 MIXING RATIO - Excellent value for both professionals and occasional users with a highly concentrated formula. The 1:100 dilution ratio means just 50 ml of solution is enough for 5 litres of water. Ideal for high-volume cleaning jobs and helps lower overall cleaning costs without compromising on performance.
  • YIELDS 500 LITRES OF CLEANING FLUID - With one 5 litre bottle of UNGER’s Liquid, you can mix up to 500 litres of cleaning fluid. Simply add the liquid concentrate to water and start cleaning.
  • SKIN FRIENDLY pH NEUTRAL SOAP - The window-cleaning soap is also pH-neutral. So not only is it easy to rinse, but it's also kind to your skin and won't cause irritation. Equipped with a secure, child-proof safety lid to prevent leakage and prevent children from opening.
