Radiator Flush Question

[probear]

OK, read up on the citrus flush and only have one question. I realize that the proper procedure is drain, fresh flush, soap (de-oil) flush, fresh, citrus flush (2.2 lbs), the really good flush, add approx anti freeze, approx 50%.

The question is "will it hurt to leave the citrus flush in overnight?" Most of my mileage is at night, so, I want to get up to adding the citrus flush, then go on my nightly commute, which is probably one hour each way. Then the next morning, warm up the car, then continue with the rest of the procedure. BTW, the nights are staying in the low 80s...

Any real problems with doing it that way? Comments?
