Fatty milk

Does anyone else have a hard time getting their parts and bottles and pieces clean bc no matter how much you scrub there’s a residue from the fat content of your milk? I scrub, I soak, I scrub again and again and again and it takes forever to get that fatty residue off anything that has contact with my milk. Some times I end up having to scrub the same thing 3 different times in scalding water and it seems like there’s still fatty traces. The insides of bottles and nipples and the head of the pump are so hard to get fully clean. I can’t let my partner clean any of it bc he’s a “it’s good enough” dishwasher and I’m a “there’s a speck so it’s still dirty” dishwasher. I’ve learned to throughly look at silverware and bowls and stuff bc he will “wash” dishes in cold water and it’s so gross, and so I always doublecheck in case I happen to grab something he washed. I try to wash anything for the baby right then and there but sometimes he’ll beat me to it. That makes me so mad bc if I’M having difficulties washing baby pieces due to my fatty milk, then I KNOW whatever he washed is still 100% dirty… does anyone else have this issue? What do you do to get the things clean? I don’t want to boil bc it breaks materials down faster and I’m not rich. But I find myself spending hours scrubbing bottles and pump parts
