To get white tablecloths white again, you need to follow a few essential steps. First, it's important to pre-treat any stains on the tablecloth. You can use a stain remover or a mixture of baking soda and water for this. Apply the mixture or remover to the stain and let it sit for a few minutes before washing.
Next, wash the tablecloth in cold water with a mild detergent. Cold water is essential because hot water can set stains. You should avoid using bleach as it can weaken the fabric and cause yellowing over time. Instead, you can add a cup of distilled white vinegar to the wash cycle, which will help to brighten the white color.
After washing, avoid drying the tablecloth in direct sunlight as it can cause yellowing. Instead, dry it in a dryer on a low setting or air dry in a shaded area. If the tablecloth is still not as white as you'd like, you can soak it in a mixture of lemon juice and hot water, then wash it again. This natural method can help to further brighten the tablecloth.
Finally, iron the tablecloth while it's still slightly damp. This will help to prevent wrinkles and will give it a crisp, fresh look. By following these steps, you can get your white tablecloths looking bright and new again.
