The Gers dropped their first points at Ibrox in the Scottish Premiership season, and could trail leaders Celtic by 11 if the Hoops beat Hearts later on Saturday.
Sam Dalby's 36th-minute header put the visitors in front, though Vaclav Cerny's smart finish levelled the contest midway through the second half.
The hosts pushed for the winning goal, with Ianis Hagi and Robin Propper denied by United goalkeeper Jack Walton later on.
Yet, despite over 70% of the possession and nine shots on target to their opponents' one, Clement's side were forced to settle for a share of the spoils.
"We need to reward ourselves, and we need to play like we played in the second half, 90 minutes long," he told Rangers TV. "Like that, you strangle teams like you did in the past, and that's the football I want to see.
"I cannot say anything about commitment in the second half, the team pushed until the last seconds to score a winner, and the goalkeeper made some excellent saves. The team was not rewarded in that way.
"It's frustrating to lose points in a game where you face one shot on target, and it's a goal. Last season, we won these games and, now, you lose points, so we need to get back to the level of before.
"They fought until the end. We had really good opportunities. You cannot ask much more, only to score the second goal. Then, you have a totally different feeling after the game."
Meanwhile, Jack Butland was left to rue what might have been, with the goalkeeper insisting he and his team-mates must up their game.
"It can't take until the second half to get going," he said. "We've got to be better. We've given away too many easy goals against teams that are just looking to hang onto something.
"It's not a great result at all. It feels like a loss. These games have got to be wins. It's not what the fans deserve from the game today. We need to do much more."
