Mortar stains on outdoor tables can be unsightly and challenging to remove, but with the right techniques, you can restore your table's appearance. Here’s a step-by-step guide to tackle stubborn mortar stains effectively.

1. Scrape Off Excess Mortar: Use a plastic scraper or putty knife to gently remove dried mortar. Avoid metal tools to prevent scratching the surface.

2. Prepare a Cleaning Solution: Mix equal parts white vinegar and water, or use a commercial concrete dissolver. For tougher stains, add a small amount of dish soap.

3. Apply the Solution: Soak a cloth or sponge in the mixture and dab it onto the stain. Let it sit for 10–15 minutes to loosen the mortar.

4. Scrub Gently: Use a stiff-bristle brush or nylon scrub pad to work on the stain. Rinse with water and repeat if necessary.

5. Rinse Thoroughly: Hose down the table to remove all residue. For stubborn residues, a pressure washer on a low setting can help.

6. Prevent Future Stains: Seal porous surfaces with a concrete or stone sealer to make future cleaning easier.

Always test cleaning solutions on a small, hidden area first to avoid damage. With patience and the right approach, your outdoor table will look as good as new!
