This is a pet peeve of mine. In fact with the advent of all this environmental nonsense getting clothes clean is really difficult. You may have noticed that whites aren't as white anymore no matter what you do . The reason for this is that detergents no longer contain Sodium Tripolyphosphate. STPP was the only real ingredient getting clothes clean. Now detergents use stuff like surfactents and washing soda-a real joke as cleaning agents go and more prone to cause fading becasue they work more in a mechanical fashion.
The worst to clean is the white french cuffs on my shirts. There is always a faint ring around them no matter what I use. A few years ago I did purchase 100 kilos of STPP and that was totally effective. My whites and especially cuffs came out looking brand new. Unfortuneately I ran out of STPP several months ago only to find the local chemical supply company that had it closed shop.
A few tips- 1)never use vinager because it stincks ( it really does) and is not all that effective. If you feel the need to use an acid, then use citric acid same effect but in contrast it smell nice just like lemons.
2) You can use TSP (tri sodium phosphate) which is easy to use but this can lead to drain deposits and clogging of machines if you have hard water. TSP is less effective than STPP.
3) use STPP if you can find it. Once you do you will never go back to anything else.
