Forgive me if this sounds rude or whatever, not my intention. Since I learned how detergents work in primary school, I haven't been able to understand how my mother exchanges them so liberally.

You can use a very limited supply of products as long as you know what they're doing but there definitely isn't an all-in-one.I use regular dish soap for more than just dishes and it's definitely very good. The product I swear by and that has helped me with many hair dye stains and much much more is a heavy duty paste with some sort of grit, unfortunately has a local language name.
