cleaning

I know this seems like a normal, mundane topic, but I found a couple of videos that really put the shine in your windscreen. First the outside: and now the INSIDE. The vid creator has loads of good tips and tricks on his YouTube page!

I bought a whole case of microfiber cloth cleaning towels at Costco - great price by the way. I now am down to a few clean ones left, any ideas of the best way to get these cloths cleanest and stain free. What cycle, temperature etc. without destroying etc. Just a few quick ideas perhaps...
