What is Selleys Outdoor Window & Glass Cleaner, and where should you use it?
Selleys Outdoor Window & Glass Cleaner is a hose-on cleaner for exterior glass, supplied in a 2 litre bottle that connects straight to your garden hose. It is formulated to clean glass for a streak-free shine, and it targets the specific mess that lands on outside glass rather than inside glass: dirt, grease, grime, fingerprints, dust, insect mess, bird droppings, chlorine and salt residue.
That list is worth reading closely, because chlorine and salt residue are the two that make it a pool-fence and coastal-window product rather than a general cleaner. The working method is spray on, let it sit, rinse off — there is no wiping, no ladder-and-bucket, and no dilution to measure.
The one hard limit to know before you buy: it is not recommended for tinted or stained glass, and coverage is up to 200 m².

These are typical values only from the product's published safety data sheet, and should not be treated as a specification. Note that the document Selleys publishes for this product is a Safety Data Sheet rather than a technical data sheet, so the figures above are physical and hazard data rather than performance data.
What the numbers mean in practice
The 2–3 minute dwell time is the number the whole job runs on. Surfaces must be rinsed thoroughly within 3 minutes, and the product must not be allowed to dry on the glass. Three minutes is a short window when you are working around a house, so the sensible approach is to treat one window or one bay at a time — spray, count it out, rinse, move on. Spraying a whole elevation and then starting the rinse at one end is how you end up outside the window on the last pane.
Weather compresses that window further. Glass in direct sun, or on a windy day, dries much faster than glass in shade. Work the shaded side of the house first, or pick an overcast day, and if a pane starts to look dry before you get to it, rinse it immediately and re-spray.
Coverage of up to 200 m² from one 2 litre bottle is a large amount of glass — comfortably a whole house of windows and doors, with room for a pool fence. This is not a bottle you need to ration on a single job.
The pH of 9–11 puts the product on the alkaline side, and that is consistent with the hazard classification: it causes serious eye irritation. Because you are spraying upward at windows, often above head height, this is a product where eye protection genuinely matters rather than being a formality. Wear protective gloves and protective clothing including eye and face protection, and wash your hands, face and exposed skin thoroughly after handling.
The hard water caveat is the one that decides whether you get a streak-free result. Selleys notes that in hard water areas a squeegee may be required to prevent water spots forming on the glass as the rinse water dries. The product cleans the glass; what marks it afterwards is the mineral content of your own tap water. If you have hard water, have a squeegee ready before you start rather than discovering the spots an hour later.
Where to use it
The product is intended for exterior glass surfaces such as windows and doors. The soiling types it is formulated to remove are:
- Dirt, dust, grease and grime
- Fingerprints
- Insect mess
- Bird droppings
- Chlorine residue
- Salt residue
How to apply it
- Test in an inconspicuous area before use.
- Keep pets and children indoors during use.
- Shake the bottle well.
- Check the nozzle is set to 'OFF', then attach your garden hose.
- Select the 'SPRAY' stream setting and turn the garden hose on to start cleaning.
- Spray sparingly onto the surface, from top to bottom in a sweeping motion.
- Let it sit for 2–3 minutes. Do not allow the product to dry.
- Switch the nozzle setting to 'WATER' and rinse off thoroughly with water, within 3 minutes.
- Turn the nozzle to the 'OFF' position, turn the garden hose off, and detach the bottle for storage.
- Squeegee the glass if you are in a hard water area, to stop water spots forming as it dries.
Limitations — where it should NOT be used
- Not recommended for tinted or stained glass. This is the clearest exclusion on the product, and it rules out a lot of modern windows, car glass and decorative panels. Check what you have before you spray.
- The streak-free claim is conditional on surfaces being rinsed thoroughly within 3 minutes.
- Scrubbing may be required for stubborn or ingrained dirt — spraying and rinsing alone will not shift everything.
- Test in an inconspicuous area before use.
- Rinse off plants immediately and thoroughly, and keep pets away from treated surfaces until they have been rinsed off.
- Avoid contaminating waterways.
