OMRI Listed

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 now excited to offer Finalsan in smaller, more home friendly sizes under the Captain Jack's Deadweed Brew label! Now you can treat your own lawn with professional-grade results!

Why is Finalsan the Best Natural Weed Killer?

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.

            It’s Mobile One. The Brand Says it All!
            Size: 5 Quart (Pack of 2), Style: Full Synthetic, Configuration: 0W-40
            I buy Mobil One 0W-40 Full Synthetic European Blend Motor oil for my three older, higher mileage Mercedes SUVs. Considering all the vehicles are running well to this day speaks to the quality of their ongoing maintenance and Mobil One lubricants have always been part of their routine. Mobil One long ago became the favored brand of both European luxury car manufacturers and their customers. I’m no exception. The product comes in a convenient handled bottle that’s easy to pour without drips or spills. It’s built in fluid level gauge provides you with a real time window into the quantity of oil you pour and quantity remaining in its container. The oil is an excellent lubricant and it’s great for my motor, too. Price wise, it’s a premium offering from a premium brand. Even so, it’s worth every penny for helping keep my vehicles running as they were engineered. I have no complaints with Mobile One and I don’t have a reason to change. I’ll keep buying it until something better comes along.

            Works great never had a problem
            Size: 5 Quart, Style: Full Synthetic, Configuration: 0W-40
            I've been using this mobile one in my 2005 Mercedes kompressor C230 w203 1.8 engine for about 18 years and never had a problem so I will continue to use it. The price was very good compared to other places but I did have to order one extra quart, I don't know why they don't make this mobile one in a six quart jug.

            Great for my hot rod!
            Size: 5 Quart, Style: Full Synthetic, Configuration: 0W-40
            Perfect oil for my hot rod! Add a bottle of zinc and you get great low temp flow as well as good heat protection. As a 0W it flows quickly for good start up protection and the 40W means I get good protection as temps rise. My car has a flat tappet hydraulic cam so I add a bottle of zinc. Has worked great!
