Tips of how to clean aluminum siding

To clean your aluminum cladding, choose a dry and windless day. First, check to see if your coating shows signs of mold, chalking, and necessary repairs. Once you have determined which cleaning method to use, try to work in the shade as much as possible.

Pressure washing aluminum siding is a good technique for ordinary dirt, grime and chalking, while washing with bleach or vinegar is necessary for mold.

Test your cleaner on a coating surface

Wear gloves to wash aluminum siding if your solution contains bleach or an aggressive cleaner. Wet a clean white cloth in your cleaning solution. Rub it on a spot on the siding and see if it is strong enough to do the job.

Turn on the pressure washer to pressure wash aluminum siding. Attach the washer to a regular garden hose. Attach the garden hose to your outdoor faucet. Start the engine.

Protect yourself

Wear protective goggles, solid shoes and long pants. Follow all instructions and safety precautions for your make and model of pressure washer. Do not clean your pressure coating if it is painted with paint that may contain lead.

Spray the coating with a garden hose. Set your garden hose to a water jet setting. Rinse the surface of a twenty-foot coating that you have just brushed. Start at the top and go down.

Attach the nozzle to fifteen degrees. Do not use settings that are thinner than fifteen degrees. Never use a zero-degree nozzle on a pressure washer. Lock the coupling securely in place.

Check the presence of mold on your floor. Look for gray, green, or black spots. Examine all grooves and bottom of liner. Look especially on the north side of the house and in places that are not very sunny.

Cover the area. Spread a tarpaulin, old leaves or canvases on the floor. Cover all shrubs or plants.

Wet the siding with a garden sprayer, if desired. Fill a sprayer with your cleaning solution for aluminum siding. Spray a portion of the coating about twenty feet wide across the entire height of the surface. Let the solution stand for several minutes before brushing this part of the coating.

Practice using the washer at a distance of about two feet. Move closer as you find the best distance. Spray horizontally or slightly at an angle downwards.

Rub the coating or increase the pressure as needed. If a low pressure wash does not work well, scrub the coating with a soap solution, then rinse it under low pressure.

Get an extensible brush. Find a brush that extends about eight to twenty feet. You can also attach a wash brush to an extendable post designed for the rollers to be painted.

Look for chalking on painted facings. Put on work gloves. Rub your gloved hand on the surface of the liner. Examine your glove for a light-colored powder.

Choose a pressure washer. Get a washer that produces a pressure of at least 2,000 psi (pounds per square inch). Plan to pick it up with a van, SUV or van if necessary. Consider getting help with loading and unloading the vehicle.
