Natural Carpet Cleaning

Hello!

I live in an apartment with carpet flooring and currently don't have the money to exchange the carpet for something more healthy like wood, etc.

And since the carpet has accumulated lots of bad stuff over the years and decades, I would now like to deep-clean it as thoroughly and naturally as possible.

Does anybody have any ideas how I could clean the carpet naturally? Any essential oils, herbs other natural substances that would be effective?

Thanks for any advice!
Blessings,
