Repent immediately from your sins right now, with a sincere repentance. Sincere repentance will wash away the sins.
Allah ﷻ says:
يَا أَيُّهَا الَّذِينَ آمَنُوا تُوبُوا إِلَى اللَّهِ تَوْبَةً نَّصُوحًا عَسَىٰ رَبُّكُمْ أَن يُكَفِّرَ عَنكُمْ سَيِّئَاتِكُمْ وَيُدْخِلَكُمْ جَنَّاتٍ تَجْرِي مِن تَحْتِهَا الْأَنْهَارُ
“O you who believe! Turn to Allah with sincere repentance! It may be that your Lord will expiate from you your sins, and admit you into Gardens under which rivers flow (Paradise)” [At-Tahreem, 66:8].
Taubat an-Nasuha (sincere repentance) implies that when you happen to commit a sin, you should feel penitent for it. Then should implore Allah for forgiveness remorsefully. And then should refrain from committing the same sin again.
