Basic Information: What is Tineacide Antifungal Foot & Shoe Spray?

This review will consider Dr. Blaine’s Tineacide Antifungal Foot & Shoe Spray. This spray is claimed to kill 99.9% of foot fungus and bacteria so it can treat conditions such as Athlete’s Foot as well as bacterial infections. It is expected to prevent nail fungus, eliminate odor and treat no-washable items like shoes sports padding, athletic gear, gym bags and so on. To learn further information on this product’s formulation and what our feelings concerning this spray were.


  • Undecylenic Acid 5%

Undecylenic Acid prevents the growth of fungus and so it is an antifungal that can be used to control such growths. This product is not diabetic friendly. There appears to be a high concentration of this ingredient in the spray so it may be effective.


Shake the spray can well before use. Two bursts should be directly sprayed into the shoe, or onto your foot, two to three times a week. Athletic gear should be treated after every use or when needed. Spray should only be used on clean, dry skin.


On the Dr.Blaine’s website, a 2 fl. oz spray bottle costs $19.99. It is possible to buy the same product on Amazon for more than half that price, or cheaper still! Amazon also offer discounts for buying products in bulk. The product is also supposed to be available to buy on although there was no such product listed when we checked.

What to Expect

A 2 fl. oz bottle is meant to have enough liquid for 500 applications according to the manufacturer. Having used this for a number of weeks, this claim is an exaggeration of how many times you can use this spray. The bottle is tiny and while the spray that comes out is a fine mist, you will end up using the whole bottle quickly, even if you are only applying it once or twice a week. It does manage to kill fungus but that is hardly surprising giving its incredibly pungent odor; that smell could kill anything. If you do not want to inadvertently inhale this and start choking on it then it is highly advisable to spray it outside. Its odor is very strong.

Keep an Eye Out

If you are allergic to the ingredients then avoid Tineacide Antifungal Foot and Shoe Spray. This spray must be kept away from eyes but if contact occurs rinse immediately with cool water. The active ingredient in this product may interact with certain medical conditions and so you should seek professional advice before using this product. Special care should be taken by those who are pregnant, are planning to become pregnant, are breastfeeding, take any prescription or non-prescription medicine, dietary supplement or herbal cures, those with allergies to medicines and foods and those with diabetes or blood vessel problems. Undecylenic acid may affect children under 18 or those with sensitive skin and so this product should only be used by them as a doctor directs them. This product should not be used on those under two without first checking with your doctor. Usage should be stopped if your condition has not improved within 4 weeks or if it in fact happens to worsen. Do not inhale this product and be aware that the mixture is flammable. What is highly concerning is that many of these warnings come as a result of additional research on our part as the manufacturer did not include many of them.

Manufacturer’s Commitment

The manufacturer does have a returns policy. There is no time limit stated on their website and no particular condition that the product has to be returned in. It can be assumed that you can return the spray after opening it. You must contact them at (800) 307-8818 in order to receive a return authorization form. This form will allow you to be refunded the purchase price of a single item but excludes tax. If bought from a different retailer such a return may not be possible. For instance, Amazon would probably not accept a return of Tineacide Antifungal Foot & Shoe Spray because it is flammable. The manufacturer does not provide any reviews for this product. However, judging by a number of reviews made on Amazon, the product is highly praised but has one major flaw: its smell.

The Bottom Line

Tineacide Antifungal Foot & Shoe Spray does what it says for the most part. It succeeds in killing infection and preventing further infection and it eliminates bad odors from shoes. Its spray format means that the product is very easy to use and allows you to treat areas that otherwise would be difficult to get at to treat. This spray also has a good guarantee, provided that you buy it straight from the manufacturer. Conditions on it are extremely limited and so making a return should be quite simple. However, Tineacide spray has its drawbacks. A 2 fl. oz bottle does not last that long, certainly not long enough for the 500 applications that the company say it can do. Considering the amount you get makes this product a bit on the expensive side, regardless of how effective it might be. This product has an extremely strong, pungent odor, which people have found to be very off-putting. The main ingredient of this is an acid that makes it possibly unsafe for some groups of people such as diabetics, who can have many issues with their feet. The ingredient is also an acid that is capable of causing irritation for a number of people, especially those with sensitive skin. In our opinion, the cons outweigh the pros in this case and we think it might be better to try finding an alternative.
