Hi,
I spoke to One-Step about this during the planning stages.
Zip it is made out of the same stuff as One-Step Concentrate - as it's the same product with a different dilution ratio.
Being a distributor for One-Step, I get am able to by bulk quantities of concentrate at a discounted rate - and then dilute the concentrate appropriately.
With One-Step, you get better results than possible with a neutral spotter, but it's still safe to leave with clients.
With regards to hazard info on the bottle, one of the advantages to using micro-splitters is that there are no hazard symbols. So it's safer for carpet cleaners, and safe to give to consumers.
All that's required on the label is 'Not Classified as Dangerous Goods'.
Hope that answers your questions.
Cheers
Matt
