Im not somewhere I can read up on that one but I only use SC as it doesn't need to be rinsed. If I remember correctly the others were not safe to spray and wipe without rinsing. As far as expiration I actually called over seas and was told this was a FDA situation. I bought in bulk and they told me its fine years past expiration and that its the US FDA that made them use a expiration date. All mine are for 2018 but I have several 64oz consitrate bottles I will continue using.
