Window Cleaner Concentrate RM 500, for Streak-Free Cleaning of Windows, Glass, Mirrors and Shower Screens, 500ml Concentrate dilutes to 4l Cleaning Liquid.

After diluting and applying the solution, I found that many of the marks (fingerprints, light smudges, general dust film) came off easily. The product lives up to its “streak-free & water-repellent” claim for these kinds of deposits. • It has a reasonably pleasant scent (not overpowering) and felt safer to use around the house than some harsher glass cleaners. • Because it’s a concentrate, a little goes a long way — good value in terms of coverage. • Combined with a decent micro-fibre cloth and a squeegee (or a proper window vacuum), the finish can look quite sharp and clean.

Good item
