Algae stains on a porcelain outdoor table can be unsightly and difficult to remove, but with the right approach, you can restore its original shine. Here’s a step-by-step guide to effectively clean algae stains:

1. Prepare a Cleaning Solution: Mix equal parts white vinegar and water in a spray bottle. Vinegar is a natural disinfectant that breaks down algae without damaging porcelain. Alternatively, use a mild dish soap solution for tougher stains.

2. Apply the Solution: Spray the mixture generously onto the stained areas. Let it sit for 10-15 minutes to loosen the algae.

3. Scrub Gently: Use a soft-bristled brush or non-abrasive sponge to scrub the stains. Avoid harsh tools that could scratch the porcelain surface.

4. Rinse Thoroughly: Wash off the solution with a garden hose or a bucket of clean water. Repeat the process if stains persist.

5. Prevent Future Growth: To keep algae at bay, regularly clean your table and consider placing it in a shaded area to reduce moisture buildup.

For stubborn stains, a paste of baking soda and water can be applied before scrubbing. Always test any cleaning method on a small, inconspicuous area first. With these tips, your porcelain outdoor table will stay algae-free and look brand new!
