i dont want to use the harsh and non environment friendly products that are recommended in the laundry sub. but i really want clean clothes. i have been washing our clothes in 30 degrees with a home made(marseille soap based) detergent but literally none of my clothes are clean.
how can i get them clean?
recommendations for a washing machine also appreciated since my machine just broke and i will buy a new one this time(only bought second hand in the past but i really want a good one now)
thanks

Context:

I have a green packet of whisper's sanitary pads and it expired this month and still more than half of the pads are not used. I noticed a few months ago that the pads will expire so I started using that and told my mom to do so but she didn't take it seriously. I have seen a news in which a girl passed away because she got an infection from using expired pads. I don't want me or my mom to get infected and not any other women to. My mom thinks that it isn't something to eat so the expiry date doesn't matter that's why she is giving this to another relative just because I refused to use it.

How should I dispose of these ? If I throw it in the dustbin my mom and dad both will get angry at me and i don't want a fight between them.
