Mineral rings on outdoor tables are a common issue caused by water evaporation leaving behind deposits. To prevent them, follow these simple yet effective tips:

1. Use Coasters or Placemats – Always place a barrier between drinks and the table surface to minimize direct contact with moisture.

2. Wipe Spills Immediately – Quickly drying the table after spills prevents water from seeping into the surface and forming stains.

3. Apply a Protective Sealant – A waterproof sealant creates a barrier, reducing the absorption of minerals into the table’s material.

4. Clean Regularly with Mild Solutions – Mix vinegar and water (1:1 ratio) to gently remove existing mineral deposits without damaging the finish.

5. Cover the Table When Not in Use – A waterproof cover shields the table from rain and dew, preventing prolonged moisture exposure.

By taking these preventive measures, you can keep your outdoor table looking pristine and free from unsightly mineral rings.
