These are worse than I thought. I used them to wash the car today. These microfibers are among some of the worst that I have ever used (I've been buying microfibers for about 10 years). When using soap, these barely lather up at all, because they are so skimpy (they apparently have fewer fibers than higher-quality microfibers. They also do a poor job of buffing. Horrible, horrible quality. Not worth the purchase at all.
I'm almost always happy with AmazonBasics products, but these are the exception. They are relatively small and fairly thin. In particular, check out costco before buying these! The ones at my local costco are much, much better.
