    Waste of time and money
  

*by L***  on Reviewed in the United States on September 23, 2023*

Product came in leaked through the box. Quarter of the product was gone. The nozzle didn’t work. Wasted 20 mins trying to get it to work. I can’t believe it costs as much as it does

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Amazing amazing for boat upholstery
  

*by K***N on Reviewed in the United States on September 21, 2022*

I didn't take before picture, but if you know 20 year old boats, you know mold grows on them over the summer and cannot be removed with simple mold and stain remover from Star Brite. This product is absolutely amazing where the mold inside the material literally disappears after hours. Sometimes it takes some heavy coating. Maybe twice on some of them. I did not take  before picture because I don't normally write positive amazing results of a product. But these photos show how clean it is after use. Yes it was full of black spots.While the product is fabulous, this shipper that ships this product is horrible. Yes don't buy it through amazon. Nozzle was broken off and no fluid was left in the bottle. Find it locally at Ace hardware. You can also get the gallon jugs which you can simply mix equal portions in a regular sprayer bottle. Much easier to do.  Believe me, if you have a boat that gets mold regularly in the summer, you need this product. My 21-year-old boat seats look like brand new!

    Concrobium Mold Control Spray
  

*by E***N on Reviewed in the United States on April 8, 2022*

Although the product did remove black mold off the ceiling surface by the back door, it left a yellowish stain that I have not been able to remove. I'd like to paint the room but don't think I can do so over the discoloration that remains. Would another productget rid of the leftover stain?Definitely wear a mask that protects your eyes when spraying overhead.
