Albertrapier,
You are missing the point. Go back and read the rest of this thread.
Any responsible house washer uses copious amounts of water to pretreat the foliage and surrounding plant life and final rinse. And using bleach in a diluted form further dilutes the product. As it breaks down in the earth it turns to organic salts, one of natures building blocks. Yes using pure undiluted sodium chloride IE salt is damaging. I am saying be responsible and conscientious how you apply your chemicals. Anything undiluted can be damaging, use a little common sense.
Take your body for an example, a little salt is good for seasoning your food and your body requires a small amount to survive, but a large dose is damaging and dangerous.

Try this test. Get you a PH meter. Test your soil before you wash. Use your biodegradable product rinse and test afterwards. Use bleach, rinse and test afterwards. I bet you will not see any difference. The reason is, you are not putting enough product on to make any difference.of change in the PH scale.

Just my .02
