I would need to know that the cleaner is effective and safe.

I would need to know what is the quality of the product and what it is made out of.

Really amazing product to clean the shoe

What material is it made of (environmentally friendly or not?) and what materials (what types of shoes) does it work on?

I'd like to know how long it takes for this product to work.

How often do I need to buy replacement cleaning supplies?

If there is residue left behind. Is it harmful to the shoe material. Does it change the color of the shoe?

I need to know the materials it works on, whether it had harsh chemicals, and that if it works on all parts of the shoe.

I need to know what it works well and gets the job done. I don’t want to buy something that is ineffective. I would probably get this information from the reviews

Is this reusable? Do I have to buy a special soap to go with the brush? How easy is it to clean the brush?

I need to know how well it works, how it works, and what it’s made of. We strive to be minimal waste and environmentally conscious so those are important things for me to know. I also want to be sure that it won’t damage my shoes.

Reviews from people that have used it on the same type of surface and fabric that I intend to use it on.

How safe it is to use on various types of shoe materials? How durable it is, or how long will it last? How to properly clean and take care of it, so that it will last longer and be more effective.

The important factor to buy a shoe cleaner product is to know the review and its brand if it's rating and suggestion are good it will be also easy to choose.

If it hs any chemicals in it I would be allergic to

If it contains harsh chemicals or safe chemicals. Sort of eco-friendly/sustainable. If the product is easy to use, or if it will take a little extra effort (multiple steps etc.)

How effective it is at cleaning different types of shoes.

How easy it is to use and how easy it is to clean up after using it. I do not want to use something that makes a mess that I have to clean up.

If it is safe to use on all types of shoe materials, or what types of shoe material you shouldn't use it on.

Is a gentle to the surfaces of the shoe. Does it include the soap? How many different types of brushes and wipes comes with it? Is it environmentally friendly? Is it good at removing stains and odors? How long do the bristles last? Are the wipes reusable?

I would need to know the ingredients and any potential safety issues with the product.

I would want to know if the product is safe for shoes and not discolor or distort the material on the shoes.

I would say the other important factor is the reviews of the product.

i would like to know how easy it is to apply and how much residue is left on the shoe

I want to know what it is made of, and if it is safe on all types of shoes or which ones it is not good to use on like leather.

Is a brush included in the kit. What ingreadients are in the product. Is it harmful to skin or do you need to wear gloves.

Other than price, the most important factor is the smell. I am sensitive to strong odors and cannot use products with strong smelly odors. The other thing I need to know is how much is in it, does it have good reviews, and the overall shelf life.

Is it good for all types of shoes? How long does it need to set before wiping?

I need to know what the instructions are and how much effort is needed to get the promised results. Before and After photos would be helpful.

I would want to know where the product is made. I would also want to know if it is biodegradable and safe for the planet.

I would need to know what chemicals are present and if it includes the brush.

I need to know if it is safe for all materials, if it has any bleaching agent ( I would rather it not), and if it has to be rinsed (I would rather it not have to be).

I need to know if it can clean all types of shoes. I also need to know how long it can usually last. Is it just a one and done, or a couple? Or lifetime? I also need to know how to clean it and if it it cleans easily. If it requires cleaner to use or just water.

I would like to know what type of shoes you should use it on. I would like to see the ratings.

Exactly what type of materials it worked on

The efficacy of the product is a big deal so I think this would need to work

I just want to see how the shoe cleaner works before and after. I'd like a video or 2 of it in use and working. Gives me more of an idea of its quality.

I would want to make sure it works well

What materials it works on

It is not have harmful chemicals if one comes into contact with.

If I was looking to buy a shoe cleaner, I would look for the ingredients in the cleaner and what type of shoe material I can use the cleaner on and of course the price.

I would need to know how safe the product was to have around young children.

I'd like to see the aggregate of reviews, and preferably also before and after pictures (or videos) of it being used on a variety of shoes.

The quality of the product would be the first thing that I would want to know.

I would like to see some text that is blunt and to the point explaining the ingredients that go into making the cleaner.

The quality of the product will be most important thing. The quality must be high when comparing to the price range of the product. And the product should be works for long-term purpose.

Mainly, I'd want to know how easily and thoroughly it cleans the shoes.
