I use a Swiffer mop and attach a microfiber towel or a regular hand towel to the holes in the back. An old diaper also works. I used to use NuFinish twice a year to wax the rv, but it was a huge job and very tiring. Now when I wash the rv I spray on Lucas Slick Mist or Turtle Wax 1 Step Wax and Dry. I do the bottom half as high as I can reach and then use the Swiffer to finish off. No more ladders and the spray on products give a great shine. I use them every time I wash and total time for our 25.5 foot rv is about 2 1/2 hours.
