I have written before about the purple rags but just had to write again.
We are a ranch family; we have cows and horses. So we have outside vehicles that are in mud often. We have a side by side that we use to check on things and the windshield gets quite muddy and dirty. I took a purple rag and glass cleaner to it. We can see out of it now!
Last night my mom was complaining about the grape kool-aid on the counter. I took a purple rag and some water and the stain was gone. She could not believe it.
