Cut an onion in half or use a slice.
Rub it directly on the glass to remove tough stains like insect droppings and dried-on dirt.
Continual rubbing will gradually clear all residues.

Finish by polishing with a dry cloth until the glass is streak-free.

Amazingly, just one or two onion slices can clean an entire door, leaving it impeccably spotless.
Onion in Water Method:
Cut an onion in half and immerse it in a bucket of water.

Let it sit for 30 minutes.

Use a cloth soaked in this onion-infused water to clean the windows.

After removing the dirt, dry the surface with a soft cloth to avoid streaks.

This method ensures long-lasting cleanliness and clarity, preventing water stains.

Conclusion:

Achieve strikingly clear windows using just half an onion, an ingredient you likely already have in your kitchen. For optimal results, consider using microfiber cloths for a final polish, enhancing the natural shine of the glass. Alternatively, crumpled newspaper can also be effective, leaving your windows sparkling like never before!
