Clear Guard Fungi-Nail Review

Manufacturer’s Claim

This Fungi-Nail review delves into the effectiveness of this drug in tackling finger and toe fungus, and athlete’s foot which commonly accompanies toe fungus. The product is said to produce visible outcomes with no adverse side effects. It works by eliminating fungal infections around the edges of toe and fingernails, cuticles, as well as under the nail tips. The manufacturer further claims the product has maximum strength and that pharmacists highly recommend it. After researching this product, do we recommend it? Find out by reading on.


The lone active ingredient in Fungi-Nail is undecyclenic acid at a concentration of 25%. The acidic substance attacks the fungi on the toenails and fingernails, eliminating it within weeks. However, being the only active ingredient in this product, its effectiveness may vary from one individual to the next.


Make sure the affected toenails, fingernails, or any other part of the foot is clean and dry before applying Fungi-Nail. Then, cut the nails in a straight line at their edge so that they are only slightly rounded at the tips. Notice that the cap doubles up as an application brush. Use this brush to apply the liquid drug onto the infected area. Make sure to rinse your hands with soap and water after the procedure. Repeat this process twice every day. Consult your physician if there are no visible changes within four weeks.


A tube of Fungi-Nail, with the new pen applicator at the time of our review could be bought on Amazon for $8.38 for 1.7 ml (about 1/20 of an ounce). The more traditional brush applicator version could be purchased on Amazon for $7.59 for 30 ml (one ounce).

Possible Side Effects

Although the manufacturer claims the product does not have any adverse effect, its active ingredient is an acid and may cause irritation. If you experience the skin irritation after using the drug, discontinue it immediately and talk to your doctor.


The manufacturer, Kramer Labs, will refund the purchase price if you are not satisfied with the results. They require you send in the receipt and proof of purchase – which could be the UPC from the label or even an empty Fungi-Nail bottle. The one thing not made explicit is a time limit for returning your purchase.

Clear Guard Fungi-Nail Review – The Bottom Line

Kramer’s Fungi-Nail, from the customer reviews on its website, seems to be an ok solution for treating toenail and fingernail fungal infection. The pros regarding this product include:

  • it is affordable
  • it comes with a money-back guarantee from the manufacturer

However, there are drawbacks which prevent us from wholeheartedly recommending it:

  • It may cause irritation for some users, since the active ingredient is acidic
  • The Amazon customer feedback ratio of positive to negative ratings is not particularly complimentary with 55% positive and 30% negative.
  • The guarantee, though present, takes too long to process (4 to 6 weeks)

We would suggest looking for a product  with better overall real-world user ratings.
