This is the second part of the verse in Arabic:

إِنَّمَا يُرِيدُ ٱللَّهُ لِيُذْهِبَ عَنكُمُ ٱلرِّجْسَ أَهْلَ ٱلْبَيْتِ وَيُطَهِّرَكُمْ تَطْهِيرًۭا

The declension is seen in two words: عَنكُمُ, which means 'from you', and يُطَهِّرَكُمْ which means 'to purify you'. As you can see in pic related, the declension of كُم which is used in both words is second-person masculine plural. This is a screenshot of my Arabic textbook (Introduction to Koranic and Classical Arabic by Wheeler Thackston, page 39).
