In one sentence, describe what the following article is about: Your rag should be wet through with white vinegar, but excess vinegar should not drip or seep from the rag. Either pour vinegar onto your rag in a sink or dunk your rag in vinegar in a bucket. Wring out the rag lightly over a sink. Too much white vinegar can cause this liquid to spread to areas of the marble that are already clean. Although this can be wiped away easily, wringing out your rag after wetting it can prevent extra work. Vinegar is a great option for removing hard water stains or built up soap scum. Place the vinegar dampened rag over the buildup or stain on your cultured marble. Make sure the rag is flat against the stain and the wet parts of the rag touch it. Allow the rag to remain on top of the buildup or stain for several hours. With especially light buildup or stains, you may be able to wipe these away in one swipe with your vinegar dampened rag. Remove the vinegar dampened rag from the afflicted area of your marble. Pour cold water from your sink into a cup or small bucket. Use this to douse the treated area of your marble. Wipe up excess liquid with a clean, soft, dry rag. Hot water in some cases can cause stains to stick to surfaces more stubbornly. Using cold water will prevent this from happening. Select a cleaning agent that is intended for marble or similar stone. This product should not have abrasives, which can scratch or compromise the finish of your marble. Follow the label directions on the product for best results. Although proper usage will vary from product to product, in many cases you can combine a product, like Barkeeper's Friend, with a small amount of water to make a paste. Apply this to remaining stains or buildup for a few hours. Generally, by allowing your cleaning product more time to work on the stain, the results will be better. However, this may not be the case with all cleaners. Be sure to check the label. Fill your cup with cold water again. Pour it on the cleaned portion of your marble and wipe up excess liquid and remaining dirtiness with a clean, soft, dry rag. After this, your counter should be clean. Polish the marble with a suitable polishing agent, such as countertop wax, and a soft rag or polishing cloth to restore its luster.
Summary: Dampen a clean rag with white vinegar. Drape the wet rag on top of stains or buildup. Rinse the treated area with cold water. Treat remaining stains or buildup with a cleaning agent. Rinse away the cleaning agent and polish the marble, if desired.

In one sentence, describe what the following article is about: You may choose how many times you prefer to rinse the tuna, but draining and rinsing it at least once is recommended. Use a can opener to open the can, but don't remove the lid yet. Holding the lid in place, flip the can over and hold it over the sink to drain the liquid. Pull off the top of the can, being cautious not to cut yourself. Take the tuna out of the can and place it in a strainer or colander. Rinse the tuna thoroughly with water, then press the water out using a clean hand or a paper towel. In a medium bowl, mash the avocado together with the greek yogurt until smooth. Stir in the tuna, onion, relish, celery, salt and pepper. lemon if using, and cayenne pepper if using. Stir until all ingredients are well-combined. Distribute the tuna mix evenly across 4 slices of bread and top each with another slice of bread to make 4 sandwiches. For a warm, crunchy variation, toast the bread before spreading the tuna mix on. You can also substitute a roll or a croissant in place of the sandwich bread. Or you can skip the bread and use the tuna mix over a salad for a lower-carb version.
Summary:
Drain and rinse the tuna. Combine the ingredients. Assemble the sandwiches.
