Iosso MOULD & MILDEW STAIN REMOVER CONCENTRATED POWDER MOLD CANOPY CANVAS CLEANER TENT AWNING

Great product , it does what it says on the tin. Great price and prompt delivery .

Does the job with little fuss, bit expensive though for what it is.

Expensive product to remove mound form our awning. Absolutely no impact on the stains I’m afraid

Cream yurt canvas cleaned with damage! I was skeptical about this product and my first try at using it failed! I tried it again and was so impressed by the results! Unfortunately I didn’t take a good before photo, I’ve attached an older photo of from a little while ago, but in recent times it had much more mildew and mold on it, Second photo is after 3 applications using a brush spaced 15-20mins apart, then rinsed with cold water and left overnight. The first time I used hot water and mixed the solution in, this did not work. Water must be cold. Results are not immediate, you need to apply it a few times, everytime it looks dry apply more, I just did 3. Then rinse it, the next day it will be transformed. Patience is key 🔑

It was ok but did not remove all the mould from the lining of my tent meaning it was pricey for the job it did.

This stuff is brilliant, in my view. It removed all the mould and mildew from a heavy duty ivory/cream canvas cover. I applied, brushed the canvas and left the product to soak overnight - the difference in the morning was dramatic. This is now my go-to product for cleaning my pop up yurt cover!

The tent was riddled with mould and dirt stains. I sprayed it on about 6 times. You need about 3-4 days for this to be effective, it’s not an instant miracle cure. I applied mine, twice a day and inbetween I put a fine mist spray on the tent to keep it wet as it’s meant to work in the wet. After the first day it lifted a few mould patches and I was really disappointed but I just coated it again twice and the next morning they were almost gone so just keep applying and keep the tent moist. I bought 4 ounces for a 6 man tent with patches on it. Just buy the 12oz cause if you’re going to keep your rent, you might need it in the future. Comes in granule form so will last forever.

This worked very well but one needs to leave the liquid on much longer than it says and keep soaking it to avoid it drying out. I also used a scrubbing brush after about an hour for the worst bits. When one rinses the mould remover off it looks like there is still some mould left but it dries with no sign of any mould remaining.

Cleaned my tent trailer auqualon canvas beautifully

My son bought a pop-up in rough condition. It had a ceiling leak which resulted in mold and water stains on the inside of the canvas. Son parked it in our driveway for his dad to help him fix it up, and I decided to work on the interior canvas. The mold and water stains were there for a long time. The before picture was taken after I had already tried cleaning it with a water/ dish soap/ small amount of bleach mixture. That did nothing. After reading other people's comments and reviews, this is how I cleaned it. I worked on a 1/4 section at a time of the canvas ceiling I made the Iosso mixture with warm water and put it in a spray bottle. I also used a sponge and spray bottle with just water. I sprayed the section to be cleaned generously with water. Then I sprayed the Iosso mixture and rubbed it in with a sponge. Because this canvas was so gross and set in, I let it sit overnight. The next morning I sprayed it with water, and scrubbed with the sponge. At first I was disappointed that the stains only lightened a little. It took several rinses with water only using the spray bottle and scrubbing with the sponge, but the canvas turned lighter and lighter. It did not remove everything, but I'm going to treat it one more time. I am giving this 5 stars because I don't think any product could have made this look perfect based on the severe mold and water stains that we had, which had likely been there for years. I'm happy with the result. The interior curtains for this pop up were also covered in mold and water stains. I first treated them with oxy clean, and ran them through the washer. No improvement. I washed them again adding two scoops of the Iosso powder with no other soap, and they came out great. It removed 95% of the stains on the curtains. It did not fade the color at all, and they smell great too.

This is a pretty expensive product given the small quantity you get. Bottom line...it won't remove tough stains from boat canvas. For example, I had a problem with a too-friendly otter hopping up on my boat, sunning itself, and bringing along its fish catch to disassemble and eat while sitting on my canvas. Then, it left the fish guts and a load of poop on the canvas. This cleaning product didn't even come close to removing those stains. So don't waste your money on it. Here's what does work unbelievably well – Cascade powdered dishwasher detergent. Get a cheap toddlers plastic swimming pool or a large plastic bin. Add hot water, sprinkle in some detergent, layer in some canvas, and keep layering in the detergent and canvas until it's all submerged. Mix it around a bit with something that won't damage the canvas, and leave overnight. Your canvas will be as good as the day it left the factory next morning. Rinse all the detergent out of the canvas and lay it out to dry.

Removed stains from canvas tent. Works great without damage to fabric or coatings.

worked great on boat top , would buy again
