When will I get clear water???

[Snowgoose71]

I drained and flushed my coolant system today (prestone superflush)....after the chemical flush I did it 3 more times with distilled water....still get color of carrot juice when I drain after running engine for 20 minutes....how many times before it drains clear???

in the picture the jug on right is the result from the chemical flush....then in progression going to the left is the result of distilled water flush. Look the same color....not getting any clearer or translucent...

appreciate any advice....not sure if I should continue to flush or not worry about it.
