Grout haze on outdoor cushions can be an unsightly nuisance, but with the right techniques, you can restore them to their original condition. Here’s a step-by-step guide to effectively remove grout haze:

1. Prepare a Cleaning Solution: Mix equal parts white vinegar and warm water in a spray bottle. For tougher stains, add a few drops of dish soap.

2. Apply the Solution: Spray the mixture generously onto the affected areas of the cushion. Let it sit for 5-10 minutes to loosen the grout residue.

3. Scrub Gently: Use a soft-bristle brush or sponge to scrub the haze in circular motions. Avoid harsh scrubbing to prevent fabric damage.

4. Rinse Thoroughly: Rinse the cushions with a garden hose or a damp cloth to remove any leftover solution and grout particles.

5. Dry Completely: Allow the cushions to air dry in the sun or use a fan to speed up the process. Ensure they’re fully dry before using them again.

For stubborn grout haze, repeat the process or try a commercial grout haze remover. Regular maintenance will keep your outdoor cushions looking fresh and extend their lifespan.
