How to clean aluminium windows

Updated November 21, 2016

Aluminium windows are a sturdier alternative to traditional vinyl or wood window frames. Aluminium is a material that has been noted for its effectiveness at cutting out noise. Over time, aluminium windows become tarnished and weathered. With proper care and maintenance, you can keep your aluminium windows looking shiny and new. Aluminium window frames may be unpainted, painted or anodised.

Add 2 to 4 drops of mild dishwashing soap to 1 gallon of warm water in a bucket. Fill another 1-gallon bucket with clean water.

Dip a soft cloth in the cleaning solution. Ring excess liquid out of the cloth. Wipe the dirt off the aluminium frame with the cloth, starting at the top and working your way down.

Dip another soft cloth in the bucket with clean water. Ring the cloth out well. Wipe the soap residue off the aluminium window frame.

Dry the aluminium thoroughly with a clean towel to prevent streaks.

Add a 1/2 cup of lemon juice and a 1/4 cup of baking soda to a bowl. Mix well with a spoon to create a paste.

Dab a clean sponge in the paste. Rub the paste on the weathered aluminium to break up deposits and grime.

Rinse the paste off the aluminium with a soft cloth that's been dipped in clean water and rang out.

Dry the aluminium frame with a clean towel, or allow the frame to air dry to create a brighter effect.


Never clean aluminium that is very hot to the touch or when it's colder than 10 degrees Carenheit. Rinse cleaners thoroughly to avoid chemical residue and deposits. Use soft clothes and towels to prevent scratches.
