MMIC-4 Instant Mold and Mildew Stain Remover (32-Ounce Spray Bottle)

Used it on boat seats for mildew and it worked great.

Wow! Worked wonders on my stucco wall that was covered in moss and mildew from overhanging trees. Took a little scrubbing with a stiff brush, but it really worked quickly. Almost instant gratification. I am repurchasing to make sure I have this on hand for the spring season. I had tried bleach before, which worked, but also discolored the stucco wall. This is a real find!

The cleaning power of this stuff is amazing..my TJ Jeep wrangle tan top was so mildew I thought it would never come clean again...this stuff is amazing

Use in well ventilated area! Worked great for removing the mold off my camper canvas. Very effective!

This product is amazing!! I wish I had taken a before picture of this garage door, which was covered in a black mold that did not come clean when I used a house wash. But once I sprayed it with this product, it immediately started working in seconds without scrubbing and now the door looks like new! It was amazing to see. The picture of the gutter is with the left section being cleaned and the right side untouched so you can get a comparison. For whatever reason the product did not work as quickly on the aluminum gutters but still impressed with the results. CAUTION: The neck of the bottle broke while holding it before I even got to use the product, so I deducted 1 star. Luckily, only a little of the product spilled out and I was able to transfer the liquid to an empty squirt bottle to use.

My 1st time using, it works great. Spray on and rinse off. I will buy again

This product is amazing! I tried multiple solutions to clean these bolsters from my boat and nothing worked. I actually ended up painting one cushion which looked great but then we found this product. I sprayed the bolsters and let it set for about 10 minutes. You can see the stains slowly disappear. I rinsed it off with water and that’s it! So easy and effortless! 1000% recommend trying this product.

Did not remove mold/mildew from our pop up camper canvas. Neither did it lighten the stains after I painstakingly treated the mold & mildew. We tried countless cleaners and tactics listed online. Best results came from a homemade solution of lots of fresh squeezed lemon, lots of course salt, mixed in water, scrubbed with scrub brush. Did 2 rounds of this (to be thorough), soaking the affected canvas, letting dry, then thoroughly rinsing. Killed the mold and mildew, greatly lightened the stains but didn't fully remove all the staining. Downside is you have to reapply waterproof solution to the treated areas when using the lemon/salt/water scrub. Irritating that this product can be shipped easily enough but doesn't qualify for returns even though a very very small amount was used to sample its effectiveness.
