Finalsan® is a patented fast-acting weed, grass, algae, and moss killers that represent a new class of products for organic weed control that do not contain glyphosate or other toxic chemicals!  Utilizing concentrated and potent and non-staining fatty acids (soaps), Finalsan is a non-selective herbicides and the best new top-of-the-line technology for fast-acting and through killing or suppression of many common annual, biennial, and perennial weeds, algae and mosses. A great organic product for use when conventional herbicides are banned or not desired!

We are excited to also now offer Finalsan in smaller, more home friendly sizes under the Captain Jack's Deadweed Brew Brand. You can now treat your own lawn with professional products and  professional-grade results!

 

 


How Does Finalsan Work?

 

Herbicidal soaps work by penetrating the waxy cuticle of plants, causing the plant to dehydrate and die. The active ingredients accumulate in plants and cause intracellular damage, leading to cell death. Activity is non-selective and will kill plants the soap comes into contact with, but will not translocate to underground portions of the plant or harm the bark of mature, woody plants.  Can be safely sprayed around the base of trees, shrubs, hops, grapes without worry.  

Use on weeds within vegetable and flower gardens, landscaped areas, lawns (for spot treatment only), in the vicinity of small fruits and fruit trees, around and on buildings, sidewalks, fences, bark mulch, driveways, patios and gravel.  Use on moss and algae, around and on buildings, roofs, decks, sidewalks, fences, bark mulch, driveways, patios and gravel. Finalsan can even be used in cool weather. Areas can be planted five days after treatment.

Finalsan reduces tree toxicity risks and leaves no harmful residue in the soil. It won’t stain bricks, concrete or asphalt and people and pets can re-enter areas once spray dries.

    Fantastic product
    Size: 8 Fl Oz (Pack of 1)
    Works Great, at first didn't believe all the reviews, I've bought 5 chainsaws from one season to the next. After each winter couldn't get them to start. Followed the instructions to flush and let sit for a few days. Every one started and ran great. Hands down, this is a remarkable product for cleaning out blocked fuel systems from sitting all winter would recommend it for all 2 cycle engines and use the stable blend for winter as well as anytime use to prevent fuel spoilage.

    Efird, a great product
    Size: 8 Fl Oz (Pack of 1)
    Used this in a Troy Built Garden Tiller, the tiller would stall and hard to crank until we use the Sta Bil Fast Fix, tiller now runs great and does not stall.

    Worked great, saved me hundreds.
    Size: 8 Fl Oz (Pack of 1)
    I've had issues with the carburetor on my 2003 Honda ATV for years. It has needed cleaned regularly to stay running, and one repair shop wanted over $400 to replace the carburetor. One treatment with STA-BIL and it's running smooth again. Very impressive.

    Great for 2 cycle, meh for 4 cycle.
    Size: 8 Fl Oz (Pack of 1)
    This stuff is flat out amazing for 2 cycle small engines, works like advertised. 4 cycle isn't as good, if your engine hasn't ran in years, you'll still have to clean the carb, but it does help some. The 2 cycle oil for one is a lubricant and inhibits varnish buildup (especially a synthetic premium brand), and usually premium oil has a fuel stabilizer in it. Plus if you don't have a float bowl, there's not enough fuel for phase separation. I also use it in my mix for my ultrasonic cleaner when cleaning carbs. Overall a very good product, but understand it's limitations in this modern age of ethanal fuel.

    It works well.
    Size: 8 Fl Oz (Pack of 1)
    Great product that delivers on what it says it does. This won’t fix a mechanical problem or damaged component, but it will fix a stuck float, varnished tank, gummed up jet, or partially blocked emulsion tube.
