We recommend checking and cleaning your aluminum railing once per year in normal environments. In more hazardous environments or if heavy soiling occurs, more regular cleaning may be required. To clean, wash the railing with a solution of warm water and mild detergent and rinse to remove all residues. The railing should be cleaned using a soft cloth or sponge. Test the cleaner in a small, inconspicuous area prior to applying it to the entire railing system to ensure that no color change or damage will occur.
