Hard water spots on a tempered glass outdoor table can be frustrating, but with the right techniques, you can restore its shine. Here’s a step-by-step guide to tackle those stubborn stains:

1. Vinegar and Water Solution: Mix equal parts white vinegar and water in a spray bottle. Spray the solution onto the affected areas and let it sit for 5-10 minutes. Scrub gently with a soft microfiber cloth or sponge, then rinse with clean water.

2. Baking Soda Paste: For tougher stains, create a paste using baking soda and water. Apply it to the spots, let it sit for 15 minutes, then scrub with a non-abrasive cloth. Rinse thoroughly to avoid residue.

3. Commercial Glass Cleaners: Use a high-quality glass cleaner designed for hard water stains. Follow the product instructions and avoid harsh scrubbing to prevent scratches.

4. Prevent Future Spots: Dry the table after rain or watering nearby plants to minimize mineral buildup. Applying a glass sealant can also help repel water and reduce spotting.

For persistent stains, consider professional-grade products or consult a glass care expert. Regular maintenance will keep your tempered glass table looking pristine.
