Hajj without lewdness or wrongdoing, and umra to umra

الحج بلا رفث ولا فسوق، والعمرة إلى العمرة

Whoever performs the hajj for God without lewdness or wrongdoing returns as on the day his mother bore him, in Abu Hurayra (may God be pleased with him)'s narration in al-Bukhari Sahih al-Bukhari 1521 — forgiveness of past sins; and umra to umra is an expiation for what lies between them, while the accepted hajj has no reward but Paradise, in Muslim Muslim 1349 — Umrah to umrah expiates between them; accepted hajj's only reward is Paradise. The first is a full clearing of the record; the second wipes out what falls between two acts.
