Problem w/using gaudy crap clothes as cleaning cloths/rags is that cheap flimsy stuff is made from synthetic materials aren't even good at absorbing spills or dust and dirt.  Maybe there are some homeless pets in the neighborhood that could use a sweater?  Or put one of the fabric tarps over your Weber BBQ grill as a cover? Or slice the ugly fatty clothes  into strips, braid 'em into a rope and make a nice Early American style rag rug?  LOL.
