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.

            Good, irritant-free face wash, decent lather
            Size: 8 Fl Oz (Pack of 1)
            So far so good. My dermatologist recommended this brand as a daily skincare routine, and I think I’ll be using it from now on. I had been using CeraVe for quite some time, and it seemed to work okay, but I like the lather VANICREAM provides. It results in a cleaner feel even if it is a placebo effect. I also prefer the irritant-free formula just because it puts my mind at ease using something without unnecessary ingredients, not because I absolutely need it. Side note: My doc recommended this during a perioral dermatitis flare-up caused by medication. The CeraVe was potentially irritating my skin even more at the time. Otherwise, I would’ve just continued using the CeraVe. This appears to be good for extremely sensitive skin, including dermatitis and acne flares.

            Love this!
            Size: 8 Fl Oz (Pack of 1)
            I’ve been using this cleanser for a little while now, and it’s honestly made such a noticeable difference in my skin. The first thing I saw was how much brighter and more even my skin looked after just a few uses. It gives that clean, fresh feeling without making my face look dull or stripped. I also have pretty sensitive skin, so I’m always nervous trying new products, but this one has been super gentle. It doesn’t cause any irritation, redness, or tightness, which is really important to me. My skin actually feels calm and balanced after using it. The texture of the cleanser itself is really nice too—it’s creamy and smooth, and it feels kind of comforting when you apply it. It glides on easily and rinses off without leaving any weird residue. After washing, my skin feels soft, hydrated, and really clean. Overall, this is one of those products that just feels reliable and soothing, and I genuinely look forward to using it every day.

            Great product! 🧴
            Size: 8 Fl Oz (Pack of 1), Size: 8 Fl Oz (Pack of 1)
            I must admit that this is my go to alternative cleanser to La Roche Posay and Bioderma but that is by no means to suggest that it is ineffective. Quite the opposite! This is one of the most gentle, fragrance free cleansers out there, and it truly delivers on its promises: removing makeup and hydrating the skin. It is suitable for sensitive skin and those with rosacea! An excellent product offering great value for money!
