A great alternative to paper towels - one sponge can outlast more than 30 rolls. And with 50% of the scrubbing fibers made from agave plant, it's a choice you can feel good about. Sanitize in the dishwasher.
I use these to clean and polish my sinks, I have a special one I use for my cook stones only, I scrub up potatoes for baking, I use them to clean tub grime and I use them to clean tennis shoes. I can easily use them for over a month and if they get dirty or smelly I soak them in the sink with cold water and vinegar. If you really need a deep cleaning of them toss them in the top shelf of the dishwasher.
