Therefore, you should never wash windows with newspaper

FIn the past, people cleaned window panes with newspaper because the paper contained ammonia in the printing ink, which is a good detergent. But because ammonia is toxic, today’s newspapers are printed without the substance. Therefore, using newspaper is pointless, it can even make the windows dirtier.

Do this instead:

Mix your window cleaner with water, vinegar, and washing-up liquid:

• Fill a spray bottle with 5 dL of warm water.
• Pour half a cup of vinegar (24%) into the bottle.
• Mix in a few drops of washing up liquid.
• Shake the bottle to mix the ingredients.

Then get out the window scraper, sponge, razor, bucket of water, towels, dishcloth, and screwdriver.

Remove the accumulated grime from the window with a razor blade, then spray glass cleaner over the entire panel. Wet a sponge and scrub the glass. Pull the window squeegee from top to bottom, sweeping the squeegee with the towel after each length. Wipe the edges of the window with a dry cloth.

Also remember to open the window, for example with a screwdriver, and clean the inside in the same way. It’s a good idea to put towels on the floor before you start, as they may splatter.
