The Hawkeyes used a 46-1 advantage in takedowns to record their first Big Ten shutout since a 44-0 win at Michigan State in January of 2017.
Iowa had four falls, three in the first period, won two matches by technical fall, and two more by major decision.
Pat Lugo opened the dual with 10 takedowns in a 23-8 technical fall at 149. Kaleb Young scored two takedowns and two nearfall points in the first period at 157 and went on to a 10-4 decision. Young finished with more than four minutes of riding time.
The Hawkeyes extended their team lead to 20-0 with consecutive falls at 165 and 174. Alex Marinelli led 5-1 in the second period before turning a cowcatcher into his seventh fall of the season. Mitch Bowman returned to the lineup at 174 scored turned his fifth takedown, a cradle, into a first-period fall.
Cash Wilcke scored nine takedowns in the final four minutes to earn a 23-9 major decision at 184. It was Iowa's fourth bonus-point win and gave the Hawkeyes a 24-0 win at the break.
The second half looked much like the first, with Iowa winning all five matches in an identical sequence -- technical fall, decision, pin, pin, and major decision.
Jacob Warner scored 11 takedowns in a 29-0 technical fall at 197. In the only match of the night featuring ranked opponents, seventh-ranked Sam Stoll's third-period escape was the difference in a 1-0 win against No. 9 Yousiff Hemida at 285.
Spencer Lee and Paul Glynn strung together first-period falls at 125 and 133. Lee needed just 30 seconds to register the fastest fall of his career. Glynn scored a pair of takedowns before getting the fall in two minutes, 46 seconds at 133.
Max Murin put the final touches on the evening with a 12-3 major decision at 141. Murin scored five takedowns and finished with more than three minutes of riding time.
"It's never as easy as it looks," said Iowa head coach Tom Brands. "Our guys came out and made it look easy, set the tone. I saw some things that caught my eye that were very positive. Now we look ahead to Indiana. We have a senior night event coming up and we have to be ready."
Iowa hosts Indiana on Feb. 15 at 7 p.m. (CT) at Carver-Hawkeye Arena. The Hawkeyes will honor seniors Mitch Bowman, Perez, and Sam Stoll following the dual. For tickets, click HERE.
