Whiter than white

Tried this from Pinterest.

Put whites in very hot water with 1 cup bleach, 1/2 cup borax, scoop of finish dishwasher powder, cap of laundry powder..
I used less as only had one grungy white nylon top.
It has come out a beautiful creamy white.
Have tried bleach and napisan before, but this worked.
I am now soaking my white nylon shower curtains.
