How to Clean Algae From Porch Railings
Fill the bucket with water and biodegradable cleaner as indicated on the manufacturer's label---generally a 1-to-1 ratio.
Dip the brush into the cleaning solution.
Scrub the areas of the porch railing covered in algae. A circular motion works well to loosen up the dirt, algae, mildew and grime on the porch.
Spray the railing with the power washer. This will remove all the dirt, grime, cleanser and unsightly algae. Start on one end and work your way across at a slow, consistent pace. Wash the railings from the top down, making sure to get into any groove that may contain algae to prevent its premature return.
Tips & Warnings
- Remove algae when the weather is warm and dry. Though not always possible, this will help to prevent the algae from returning as quickly. Though some people use it on algae instead of cleanser, bleach is a harsh substance that may discolor wood and affect finishes.
