I had the dreaded green coolant and decided to replace it. I drained, flushed, degreased, flushed several more times, did the citric acid, rinsed thoroughly with water and have flushed three additional times. For each flush I've opened the block drain and pulled off the lower radiator hose. The problem is although the water looks clear when draining, it has an amber color when in the bucket. It does not feel slippery to the touch. Should I continue to flush until the water is clear in the bucket or is the amber color acceptable?

Thanks.
