ZoutLaundry Stain Remover - 12 fl oz (354 ml)

Q: What is the difference between the $4 and the $9 bottle of Zout?

The $4 one with a blue nozzle sprays out a runny liquid and the $9 one with a red nozzle is foamy when it sprays out, so it's not as runny. I have purchased both the spray and the foam at a local store and I don't think there was such a price difference between the 2. I think the price difference is just on Amazon. They both work well, but I really think the foam version bottle runs out faster, even though they're both 22oz bottles.

Q: Which is the best version of the zout stain remover to get? the foam or the spray, or i just heard it comes in a gel form. where?

I have used the zout spray for many years. I am very happy with it. The product has a pleasant scent and is an excellent stain remover. I have not used the gel.

Q: sis there a grease remover

It's the best product I've found to remove grease. not saying it's perfect--and sometimes it takes 2 or 3 washings--but it's pretty good at removing grease.
