OK you guys seem to have at least taken your basic high school chemistry class that I skipped.
Is this the same stuff that they sometimes display on endcaps at the big box hardware stores maybe with a video showing them hosing off stuff with it?? If so I have been avoiding it due to the phosphates. I recall being told that the reason we see "suds" floating down the river or building up near the shorline is due to phosphates. Same thing?? If so I have to wonder why we're readily dumping more of it into our water system just to save a little elbow grease.
I'm not trying to be critical, just honestly trying to learn and "voicing" my thoughts at the same time.
THANKS!!!!
