I assume you’re washing with warm to hot water?
Either your dish soap sucks ass, or your technique does if washing doesn’t get rid of grease and oil the first time.
Pro tip: use an actual soap bar, the one you wash your hands with. Works way better for oils, and particularly specifically on plastic.
Where I am, there are also soap bars for household tasks, with a shitload of acid in them. Would probably clean oil even better
End the microplastic pollution, use glass or metal
My wife is starting to get really irritated with me as I begin my recycled jar collection.
The problem I foresee is that most of my old salsa jar lids will eventually rust and I’m not sure what to replace them with.
Glass recycles, so you could recycle the jar and replace it
You could also use beeswax wraps, or a silicone sheet and a tie
If you need the sterility of a sealed jar, I imagine you’ll just need to replace them over time
In this scenario I would add some dishwasher powder to some hot water and leave it for a while, the enzymes digest the fats and can be much more effective in some circumstances

Should get glass or metal containers (ore sometimes even ceramic) if you can afford it or if you can sneak them into your bag/inner coat pocket.
I bought some when I could afford it ~five years ago and they’re still like new.
…You have to take out the sealing band and wash it separately from the lid. So many containers are ruined because people don’t take out the seals and the grow mouldy. ;-;
Have you considered it is not the dish but perhaps your greasy sausage fingers?
Food for thought.
Mmm greasy sausage finger

I like my fingers deep-fried. Slides right of the bone.
That’s when it becomes a problem for the dishwasher.
