How to Clean Egg off a Window
Egg on glass is more than an eyesore — left too long, its acidity can genuinely etch the surface, and sunlight can bake the protein on hard enough that it turns from a five-minute job into a real one. Speed and the right method both matter here.
Why speed matters
Egg whites and yolks are acidic, and given enough time sitting on glass, that acidity can etch the surface — a mark that no amount of cleaning afterwards will fix. Sunlight makes it worse: the heat can effectively bake the protein onto the glass, turning what would have been a quick wipe into a genuine scraping job. The moment you spot it is the best moment to deal with it.
The method
Rinse with lukewarm water first — never hot
Hot water can actually cook the egg onto the glass, making it stick harder rather than loosening it. Lukewarm water softens it without that risk.
Let it soak
A wet sponge or cloth held against the residue for a few minutes gives the moisture time to soften it properly before you touch it with anything else.
Wipe gently
A soft sponge or cloth, not anything abrasive, lifts most of the softened residue without risking scratches.
For anything left, use a vinegar solution
Equal parts white vinegar and water, sprayed on and left for a few minutes, breaks down the remaining protein. Wipe again once it's had time to work.
Finish with soap and water, then rinse and dry
A final clean with mild dish soap and warm water removes any leftover residue and vinegar smell. Rinse with clean water and dry with a cloth for a streak-free finish.
If it's already dried and stubborn
For egg that's had time to properly dry on, gently loosen the bulk of it first with a plastic scraper or dull edge held at a shallow angle — never anything metal or sharp, which risks scratching the glass. If it's still not shifting after soaking and scrubbing, rubbing alcohol on a cloth cuts through residue that soap alone can't manage. A paste made from bio laundry detergent and a small amount of water is another option professional window cleaners sometimes reach for on genuinely baked-on cases.
Reducing the chance it happens again
Egging tends to cluster around Halloween and Bonfire Night in the UK, so a little extra vigilance around those dates goes a long way. Motion-sensor lighting and visible security cameras are genuine deterrents, and a quick word with neighbours to keep an eye on each other's properties during the period helps too. If you're hosting guests, it's worth a gentle word beforehand about not getting involved in any egging themselves.
Don't let it sit and etch
If egg or any other residue has already left a mark, our window cleaning covers streak-free glass throughout your property — inside and out.
Frequently Asked Questions
Can egg permanently damage a window?
Yes, if it's left long enough. The acidity in egg can etch glass over time, and this kind of damage doesn't come out with cleaning — speed matters more than almost anything else here.
Why shouldn't I use hot water on egg residue?
Hot water can cook the egg protein onto the glass rather than loosening it, making the job harder rather than easier. Lukewarm water is the safer choice.
What if the egg has already dried hard?
Soak it longer before attempting to remove it, gently loosen the bulk with a plastic scraper, then follow up with a vinegar solution or rubbing alcohol for anything that remains.
Can I use a metal scraper or razor blade?
It's best avoided. A plastic scraper handles most dried egg without the risk of scratching that a metal blade carries.
Does vinegar work on all window types?
It's safe for most standard glass, but test an inconspicuous area first if your windows are tinted or have a special coating, since some finishes can react differently.
