Window & glass spray
This spray is designed to dissolve mineral deposits and soap residue — the stuff that leaves streaks on your windows and glass, and cloudiness on shower screens. It's citric acid doing the work here (works like vinegar), just without the smell.
The recipe
Tap or pre-boiled water is generally fine. If you have hard water, use distilled or demineralised water instead.
Add the ingredients to a spray bottle, shaking well to dissolve.
Tips for best use
If the glass has visible grime, fingerprints, residue, or a greasy film, an acidic spray on its own won't give good results. That layer needs to be removed first.
Clean the surface with a multi-purpose spray or paste first. Once the glass is clean, follow with this acidic window and glass spray as a finishing step. This two-step approach prevents streaking and stops residue from being spread around the surface.

Can I use vinegar instead?
Yes — diluted or undiluted vinegar works as an alternative to a citric acid solution.
