Not all cleaning solutions are appropriate for all surfaces. To determine how to best clean the painted aluminum doors and windows in our home, I asked for several opinions. After speaking to the customer-service departments of Lowes and Home Depot, two major home improvement centers, I then contacted a manufacturer of aluminum doors and windows. All three gave me the same answer. Their recommendations did not include abrasive or harsh cleansers that could remove the paint. Here's how to go about it.
Fill one bucket with warm water about three-quarters full.
Add mild detergent to the water, using the water-detergent ratio recommended by the instructions on the detergent packaging.
Fill the second bucket with warm water.
Wash the aluminum, using a soft rag and the soapy water mixture.
Use the second soft rag to rinse the washed area with warm water from the second bucket. Remove all the soapy residue with the clear water and rag.
Use the towel to dry the surface that has been washed and rinsed.
