Quantitative analysis Test 1: Absorbency To measure absorbency, we conducted two separate tests — one for water weight and one for volume.

Weight First, we weighed a dry sheet of each paper towel.

We then saturated the sheet with water, held it up until the water stopped dripping from the bottom edge, and weighed it again to see how much of the water remained within the sheet. Brawny came out ahead in this test, holding 0.

Close runners-up were Bounty and Viva, each with 0. Volume Our second test determined how many sheets each brand needed to completely absorb two ounces of water, by volume.

We poured the two ounces onto a wide plate and used a consistent motion for each brand to drag quartered sheets until the plate was completely dry to the touch. Brawny, Bounty, and Viva all completed the task using just two and a half sheets, pulling ahead of the other three brands.

Using this sheets-per-ounce data, we were able to calculate the cost per ounce of liquid absorption for each paper towel. The single-ply products — Viva and Scott — were the most expensive in terms of cost per ounce of liquid absorption.

Strength Next, we wanted to test the strength of each brand by seeing how much weight it could support before breaching. Bounty earned first place in this test, holding pennies, or Brawny was the next strongest, holding pennies, or The other four brands were substantially weaker, all breaking under the weight of pennies, or 9.

Durability Finally, we wanted to discover which brand could hold up to tough jobs the longest. Using medium-grade, coarse sandpaper, we tested how many swipes a sheet could handle until it wore through. After folding each sheet three times, making eight layers of the paper towel, we dragged a sanding block across each sheet, using consistent speed and force to drag the sanding block with a string.

We then checked for tears after each swipe. Again, Brawny and Bounty distanced themselves from the competition, withstanding 13 and 12 swipes, respectively.

Viva shredded after six strokes, White Cloud and Great Value lasted just five, and Scott wore through after four. Qualitative analysis The experience of using a paper towel involves much more than just measurable data.

To evaluate overall user experience, we cleaned windows, used them as napkins and facial tissue, soaked up bacon grease, and scrubbed dried red wine off the kitchen floor.

Glass cleaning ability With the midafternoon sun shining in, we cleaned sliding glass doors using glass cleaner and one sheet of each product. We wanted to see how easily each towel removed dirt, how it held up under wet cleaning solution, and if visible streaks were left behind on the glass.

In this first test, Viva joined Bounty and Brawny in the top tier, performing better than the other three products. These top three towels, Viva in particular, have more texture than the others, with grooves and divots, making it easier for them to pick up dirt, grime, and grease from surfaces.

All three stayed strong and left the glass free of streaks. Scott and Great Value are thinner than the other brands and, therefore, absorbed less of the glass cleaner.

In a pinch, both paper towels can comfortably replace napkins and facial tissue. Grease absorbency Next, we fried bacon in a hot pan pulled out two strips with a slotted spatula and placed them on a sheet of paper towel, which was directly on the kitchen counter.

After folding the sheet over the bacon to blot the grease, we checked out the absorbency. There was a fainter remnant of grease under the Viva and Great Value towels, which could be felt but not seen. There was also a trace bit of grease left on the counter by the Brawny towel. A sheet of Bounty appeared to trap the most grease from the two strips of bacon, and the spot on the counter under it was dry to the touch.

We then tackled the six dried stains with one sheet of each brand. Viva, Brawny, and Bounty each remained strong.

In fact, all three picked up the wine relatively quickly and easily without having to exert much pressure. Again, the more textured surface of these three towels probably explains their superior performance in this test.

The other three brands did eventually succeed in removing the spots, but only after increasing the pressure and number of swipes across the spill. Our hands went right through the Scott and White Cloud sheets as they thinned and shredded during the cleaning.

The best paper towels overall Two brands stood out as top-of-the-line products after assessing the quantitative and qualitative data: They were tougher, absorbed more water, cleaned up messes easier with less sheets, and distinguished themselves as better than the rest overall.

We give the narrowest edge to Brawny for its soft feel, durability, and absorbency — for a price that beats Bounty.Water absorbency is a measure of the amount of water absorbed by the wetted surface of paper and board materials.
