InshaAllah there is nothing wrong to learn through videos and practice the movements with your friend through facetime so you can correct each other.
Just make sure it's the right video. I would suggest
If it's possible to go to the masjid then go there. You can still learn how to pray while being cautious with distance, mask.
You have to wash hands in wudhu anyway, so you can use soap and water.
You know without ablution, major or minor, your salat is invalid.
