| Cleaning Aluminum Information |
Use mild a detergent and warm water when possible. Alkalis, even baking soda, and especially stronger alkalis discolor aluminum. If trying a stronger cleaner, pre-test on a hidden place to be sure it cleans satisfactorily and does not damage the aluminum. Always follow directions on the product label for aluminum, EXACTLY.
Be cautious about using abrasive cleaners (scouring powders, steel wool, abrasive polishes, etc.) as they may permanently scratch aluminum; painted or anodized aluminum surfaces will be permanently damaged. Do not clean aluminum when it is too hot to touch, or if temperatures go below 50 F.
On outdoor surfaces, remove bugs, sap, tree seeds, etc. as soon as possible, as they harden with exposure to sunlight and heat, and so are harder to get off. Suitable solvents will remove tar and similar substances. Test solvent first if the aluminum is painted to be sure it doesn't also remove the paint. Follow label precautions when using solvents--no spark or flame in the area and have sufficient ventilation.
