Jamieson, Fausset and Brown on 2 Peter 2:18

18. allure--Greek, "lay baits for."

through--Greek, "in"; the lusts of the flesh being the element IN which they lay their baits.

much wantonness--Greek, "by licentiousness"; the bait which they lay.

clean escaped--Greek, "really escaped." But the oldest manuscripts and Vulgate read, "scarcely," or "for but a little time"; scarcely have they escaped from them who live in error (the ungodly world), when they are allured by these seducers into sin again (2Pe 2:20).
