This is probably the best mop I have used on my boat. It works nearly as good as my expensive chamois I use on my glass windows and isinglass and it does a superb job on the decks. A quick wring-out over the side and it is ready to go again. I was surprised to see that it did not require conditioning or washing prior to first use, but it did not streak or leave any oily marks. After drying, it remains softer than I thought it would. I might buy a second one to have a spare once they are back in stock again.
