How do I fix stained clothes

alright y'all, idk what it is but I feel like clothes here stain super easily. it's almost a guarantee that if something gets on my shirt, it isn't coming out no matter how quickly I wash it. I'm confused because I definitely didn't get stains this easily when I was still in america. does anyone have this problem? also, what's the best way to remove stains here?
