75% pure, super concentrated vinegar..

Waaaaaaaay too expensive.

I use this to make an all natural weed killer for weeds that are inbetween my patio pavers. This is strong and caustic stuff, but it works like a charm and is not worse stuff that could drift onto my edible plants. You need a mask and gloves to work with it, perhaps even goggles if using it to clean you must have a well ventilated place. I used a bit on my old enamel sink and it cleaned it better than a certain Clean Up product. The sink is already ruined so etching was not a concern. The smell is strong as you would expect and you actually need a ventilated mask like I mentioned if you will be over top of it. It is highly acidic and toxic to ingest but, can be rinsed away and the after life compared to a big name weed killer is practically zero time after drying outside or rinsing thoroughly inside. Pretty sure it will etch glossy surfaces so read the directions and use with caution. I Love the stuff! ( In the picture I am including, you can see the weeds I did not treat, The area near the screen door is where I did, and they are gone, they burn up and I just swept them away.)

This worked for our concerns about not wanting to poison the environment and managing weeds and more importantly "sucker" shoots of trees that we have had to cut down. Managing these unwanted and wildly growing suckers at the base of a tree we've had to cut down has been a real battle. In researching the internet, this product was highly recommended on several sites and I was grateful that it was easily available on Amazon. This product is not be taken lightly/casually. This is a highly toxic concentration that can hurt human beings when it comes into contact with skin, but is amazing at its ability to end our never ending battle for keeping our yard weed free. PLEASE wear gloves, safety glasses and clothing to protect yourself from any "splash" or wind drift that may happen while using this product - even if you use a fairly long wand on your weed sprayer equipment. Very effective, very strong and very much worth the price because of its effectiveness.

I bought it to kill weeds. When it arrived, the bottle had leaked all over the shipping box. In addition, it hardly worked at all. An expensive waste of money.

the concentrated vinegar is a real value. Diluted to appropriate strength is excellent cleaner, herbicide
