Question:

My doctor told me to use something to dry my feet to treat my warts. He said that if I could dry my feet that there'd be a chance that my warts would go away without surgery. is that true? Would this stuff work?

Answer:

For some reason, warts seem to thrive in a damp, dark environment. Drying the foot is an old trick used to treat warts and in many cases, it really does work. Onox would be a good choice to dry your feet. Will it work to help you eliminate your warts? Can't find out without trying.

Question:

Can I just spray this in my shoes or do I have to spray it on my feet?

Answer:

The source of the perspiration isn't the shoe, it's the foot. Sure, you'd get some benefit by spraying the shoe. But to maximize the effect of Onox, just spray on the sole of the foot.

Question:

I bought a gallon of Onox a few years back and I just fill the small spray bottles as they get low. The bottles no longer spray in a nice mist like they once did. Is there a solution I can run through them to clean? Can I order more empty spray bottles? Will off the shelf spray bottles be sufficient?

Answer:

I'm sorry that we don't have empty spray bottles for you, but I would think that off the shelf spray bottles would work just fine, since your bottle is showing signs of age and build-up of salts in the bottle. If the off the shelf one doesn't work the same, you could always just buy one bottle of Onox, and then refill it when it is empty. Glad you like Onox!

Question:

Can you use in other parts of your body?

Answer:

You sure can. One of its recommended uses is for relieving itching from bug bites.

Question:

I want to make sure that Onox Foot Drying Solution is the exact same product as Onox Foot Solution - it looks like the same bottle, but my bottle does not have "Drying" in the name of product- want to make sure I am ordering same item.

Yes, this is the exact same product. We added the word 'drying' to the product name on our website just for searching purposes, but the product is Onox Foot Solution.

Question:

Will Onox Food Drying Solution help reduce/eliminate foot sweating? I'm training for a long distrance walk and am struggling with blisters.
