Parge coat stains on an outdoor table can be unsightly and stubborn, but with the right approach, you can restore your table's appearance. Here’s a step-by-step guide to effectively remove these stains:

1. Scrape Off Excess Residue: Use a plastic scraper or putty knife to gently remove any loose or dried parge coat from the table surface. Avoid metal tools to prevent scratches.

2. Apply a Cleaning Solution: Mix warm water with a mild dish soap or use a specialized concrete cleaner. Apply the solution to the stained area and let it sit for 5–10 minutes to loosen the residue.

3. Scrub the Stain: Use a stiff-bristled brush or a sponge to scrub the stain in circular motions. For tougher stains, a mixture of vinegar and baking soda can add extra cleaning power.

4. Rinse Thoroughly: Hose down the table or wipe it with clean water to remove all cleaning residue. Repeat the process if necessary.

5. Prevent Future Stains: Apply a sealant or protective coating to the table to make future cleanups easier.

For persistent stains, consider using a pressure washer on a low setting or consulting a professional cleaner. Regular maintenance will keep your outdoor table looking its best.
