Easy to keep your patio clean!
I use Kabosh each year on my patio and stepping stones to keep them clean from the variety of mildewy/grimey buildup I get living in a north/south facing house. Easy enough to use - just spray it on and let it soak in. I love that it’s super environmentally friendly - I have lots of greenery around my patio and this does no harm to the surrounding area. The first time I used it I tested it on half my patio to see what would happen, and within a few days there was a noticeable cleaner look (see pics). I got similar results using this on our stepping stones in our yard - it’s easy to spray them and keep them clean (pic shows when I spot tested first one one stone to make sure the grass would be ok and it was). Overall, this bottle is much quicker to apply than getting out the pressure washer, and it saves water too!

Cleans As Well As Other Products
Kabosh is different from some other siding cleaners in that you spray it on and leave it be for at least 12 hours. If it is going to rain right after you spray it on, don't use it until you are sure it can be left to soak in for 12 hours. Then you can let the rain wash it over or gently hose it. If you want a quick clean, okay rinse it. It will clean off the streaks and algae, but you won't get the long time deterrent of keeping the algae and streaks from coming back quickly. Of course, I haven't tested Kabosh's long term effect since I must write the review for the Seeds Program in less than a month after receiving the product. I chose to use it and let the rain wash over it. My advice is to gently spray it off after 12 hours.

If you have days to wait for results
While my pressure washer was out of order, I thought I would give KABOSH Eco Guard Cleaner a chance on a few problem spots around the house. First of all, don't let the eco friendly part fool you. It smells strong, and the instructions tell you to spray surrounding landscaping with water before and after using. I let the mist fall on some unwanted greenery, and it dried up and turned brown. The label reads that green stains will disappear in 1-3 days. I don't know about disappear, but some did go from green to brown. I could have used the entire bottle quickly, but held on to some in case I needed a second application, and I did. I will not waste my time with this product again. The pressure washer can't be beat.
Apply to the desired treatment area and “forget it”, let nature handle the rest.
The Eco Guard advance outdoor cleaner is a great option for cleaning and removing of surface stains without much effort. It helps greatly with not having to scrub or pressure washing the surfaces after application as it self-cleans those surfaces with the use of the rain or future cleanings. Additionally, the instructions for application are very simple and easy to follow. Apply to the desired treatment area and “forget it”, let nature handle the rest. Unfortunately, this is not instantaneous, so patience is necessary. I applied it to my balcony, and it remove some of the stain after the first 24 hours of application, however, other stains including mildew took several more days to clear with additional rain and time.

The Easy Way to Clean Outside Areas
I live close to the beach and it is always damp. It's a constant battle against the mold on our walkways. This product is great! All you do is spray it on a dry area and leave it. That's it! And it continues to work for a year. I also used it on the oil stains in the garage. They were pretty bad so I'll probably need to do a second coat in a month. But for now, the stains are much better.

Works but slowly over time
This no pressure washing, scrubbing or rinsing required cleaner does work over time but I like instant gratification when cleaning. My outdoor use was on white vinyl fencing and I have a lot of it so a pressure washer is my standard go to application. Waiting days to see it work wasn't exactly what I wanted. HOWEVER, using after my initial cleaning as a maintenance application would be great. It works over time 3-6 months. It is eco and pet friendly making it ideal. The scent is strong so outdoor use only. Applications include decks & patios, sidewalks and driveways, all roof types and stucco and siding. I thought the instructions could have been a bit clearer; for example, "Apply a thorough coat of solution to affected area, keeping the surface wet as long as possible." You could use the entire bottle! I think this would be great for smaller scale applications and especially for maintaining clean surfaces.

Honest Review
Let me be honest and say, don’t base your purchase off of this review. The label directions clearly state not to apply product if rain is expected within 12 hours. Well, I had checked the forecast and it didn’t show any rain so I applied the entire bottle on our privacy fence. Wouldn’t you know within probably an hour we had an unexpected storm pass through with absolute downpours of rain. That’s been the pattern this summer in Alabama. It’s been a wet one for sure! I’d like to eventually give this product another shot. Under the circumstances I couldn’t tell that I’d applied anything at all to our fence. Oh well.

Kabosh Multi-surface cleaner
I read the direction and then looked at the bottle. They seem to conflict. One (Directions on back of can says apply DRY and no rain for 12 hours and the other (How it works) says WET the surface, apply, then WET again. I tried both. Both methods turned the green mold on the siding to gray in a day. Looking good. I watched for 4 days and not much else happened even though we got a lot of rain. After 3 days, I ‘rinsed’ part of the lower area that I applied ‘Wet’ and it seemed to clear some of the gray away. Both methods seemed to work to change it from green to grey but not much else happening ‘quickly’. I would recommend this product as it seems to have an affect on the mold growth, seems to be following the ‘directions’ and need to wait 3-6 months for it to disappear totally. It suggests a second application after one month for severe stains and I will do that as well. Will it keep the mold or algae from returning, only time will tell.

Great product!
First I was surprised at how well this Kabosh works. Every summer, the siding on my house that does not get a lot of sun, always has green mold. In the past , I would just wipe it down with bleach. This was ok, but you had to really scrub hard and the areas that had mold 8 ft. off the ground required getting a ladder. Not this year,though. I was able to eliminate the mold by just spraying Kabosh on the mold. I went back to see how it was working 60 minutes later and found it was completely gone. I just hosed off the treated area and that was it. This stuff really works great.

We live in "sunny" South Florida, however, we still experience mold, mildew, and gunk nevertheles...
We live in "sunny" South Florida, however, we still experience mold, mildew, and gunk nevertheless, and that is where KABOSH ECO GUARD ADVANCED OUTDOOR MULTI-SURFACE CLEANER FOR MOLD, ALGAE AND MILDEW STAIN REMOVAL AND PREVENTION comes in, which is available at HOME DEPOT in a 32 ounce size spray bottle; KABOSH OUTDOOR CLEANER SPRAY has instructions right on the spray bottle, so no guessing what to do or how to use it; KABOSH OUTDOOR CLEANER SPRAY is easy to use and comes in its own spray bottle; no need to hunt down nor buy a spray bottle, and no need for measuring and mixing - just spray - and wait - unfortunately, on the down side, you have to wait anywhere from 1 day to 3 days for the results, but results is what you get with KABOSH OUTDOOR CLEANER SPRAY - it "kaboshes" the heck out of mold, mildew, etc - you can use KABOSH OUTDOOR CEALNER SPRAY on decks, roofs, stucco siding, patios, or anywhere you have mold, mildew, algae, or other "gunk"; KABOSH OUTDOOR CLEANER SPRAY is bleach-free which means that it goes easy on all of your items, as well as it is eoo-friendly and pet safe; and one really good thing about KABOSH OUTDOOR CLEANER SPRAY is that it is made in America!
