Questions & Answers about Я мою грязную обувь в ванной вечером.
What does мою mean, and how is it related to the verb мыть?
Мыть is the infinitive form, meaning to wash.
Мою is the 1st person singular present tense: I wash / I am washing.

- я мою – I wash
- ты моешь – you wash (informal)
- он/она/оно моет – he/she/it washes
- мы моем – we wash
- вы моете – you wash (formal/plural)
- они моют – they wash
So Я мою = I wash / I am washing.
Why is грязную обувь in that form? What case is it?
Грязную обувь is in the accusative case, because it is the direct object of the verb мою (wash what? → dirty shoes).
- Nominative: грязная обувь (dirty shoes – subject)
- Accusative: грязную обувь (dirty shoes – direct object)
The adjective грязную changes its ending to match the feminine accusative singular noun обувь.
