These are very useful for cleaning up basically anything around the house or in the garage. They are fairly absorbent and quite strong. The roll is quite large and heavy. While you do not need a dispenser, when I first tried them I just laid them sideways in a box and pulled them from the roll as needed, one is recommended for ease of use.Due to the initial weight of the roll, about 20-25 pounds, I prefer putting the roll on the stand alone dispenser (Kimberly-Clark Wypall 80596 Black Jumbo Roll Dispenser) and not the wall dispenser.Also, these come in self-dispensing boxes (WypAll 34790CT X60 Wipers, Nylon, 9 1/8 x 16 7/8, 126/Box, 10 Boxes/Carton) that are comparably priced to this giant roll and much more convenient to use, although the ones in the dispenser cartons are not the same size as the one on a roll. The size of the wipes on a roll is about 12" x 13" and the size of the wipe in the dispenser cartons are about 9" x 17"The description on the wipes "X__" indicates the strength and durability of the wipes, with X10 being the lowest. The highest I have used is X80 and they about as strong you could possibly want for any household cleaning task. Of course, none of these towels are indestructible so always wear protective gear, such as glasses and gloves when warranted.
