Today after I finished cleaning my Mom's car I had both my new microfiber cloths sitting in a bucket of water. My younger brother who had been helping me though it would be a great idea to take them out and put them on the muddy ground next to the bucket. Now both my microfiber cloths are covered in mud and grass. I managed to get most of it out after quite a bit of soaking, rubbing, etc. But here is still a little bit left. How can I ge the rest out, or should I just replace them?
