ThomasPowers Posted May 27, 2020 Share Posted May 27, 2020 Would depend on how much it had dissolved previously. Shouldn't auto plate steel; I don't know about other metals. Vinegar is cheap in Jewelry sized amounts, why not just buy more? Link to comment Share on other sites More sharing options...
Kennneth Posted June 9, 2020 Share Posted June 9, 2020 Hi everyone, I'm removing the zinc from a 20 gallon trash can with vinegar. I like the idea of using the vinegar in the garden after removing the zinc. I have a few blueberries which would love the acid I'm sure, and I've just planted 100 norway spruce trees. I'd like to put the vinegar on these trees and berries but I'm concerned that there might be too much zinc in the vinegar. Can anyone tell me if the zinc would just be too much for my plants or if it would be OK to give to more than 100 different trees and 5 blueberries. Thanks!

ThomasPowers Posted June 9, 2020 Share Posted June 9, 2020 Got a county extension agent who might know (or can research) the plant details? Link to comment Share on other sites More sharing options...
JHCC Posted June 9, 2020 Share Posted June 9, 2020 Vinegar in the garden is a BAD idea. In the quantities necessary to change the pH of the soil, it's going to have a substantial negative effect on the beneficial microbes in the soil. Here's some useful information: http://gardenprofessors.com/vinegar-a-garden-miracle/ and http://gardenprofessors.com/a-tale-of-two-herbicides/ Link to comment Share on other sites More sharing options...
Frosty Posted June 9, 2020 Share Posted June 9, 2020 Welcome aboard Kenneth, glad to have you. If you put your general location in the header you might be surprised how many members live within visiting distance. Ditto John, that's WAY too much vinegar, especially in one dose. It'd probably take months to introduce it slowly enough to not degrade the fertility of your soil. Microbe make dirt into soil. You don't want to make soil into dirt. Frosty The Lucky.

Weldergirl88 Posted July 15, 2020 Share Posted July 15, 2020 Can vinegar take off or help rust Link to comment Share on other sites More sharing options...
SLAG Posted July 15, 2020 Share Posted July 15, 2020 W.- girl, Check wiki with the search phrase "rust removal" let me quote a bit of it. "Rust removal from small iron or steel objects by electrolysis can be done in a home workshop using simple materials such as a plastic bucket filled with an electrolyte consisting of washing soda dissolved in tap water, a length of rebar suspended vertically in the solution to act as an anode, another laid across the top of the bucket to act as a support for suspending the object, baling wire to suspend the object in the solution from the horizontal rebar, and a battery charger as a power source in which the positive terminal is clamped to the anode and the negative terminal is clamped to the object to be treated which becomes the cathode.[13] Rust may be treated with commercial products known as rust converter which contain tannic acid or phosphoric acid which combines with rust; removed with organic acids like citric acid and vinegar (a.k.a. acetic acid), or the stronger hydrochloric acid; or removed with chelating agents as in some commercial formulations or even a solution of molasses."

What are you wishing to derust, it can make a real difference. Frosty The Lucky. Link to comment Share on other sites More sharing options...
ThomasPowers Posted July 15, 2020 Share Posted July 15, 2020 Vinegar is an easy to source and use rust remover but you need to have full immersion of the piece otherwise you get an etched in line where it crosses the liquid/air boundary. So better for smaller items. As long as you are just removing rust then disposal of the used solution is fairly easy. I used to pour it on my limestone gravel driveway for weed control. Once you have a sealeable tub of it it can be reused until it slows down to inefficient times. DO NOT use it in the shop as the fumes promote rust on items like tools!

Frazer Posted July 15, 2020 Share Posted July 15, 2020 I have a larger glass tupperware container with a lid that I keep full of vinegar for removing forge scale, rust, galvanization from various things. The glass is just so I can look inside and for easier cleanup, not because a plastic one wouldn't work. When it's used up, it seems to last a pretty long time, I just dump it in the woods.. maybe that's not the best disposal method, but considering what's in the container and the volume of liquid (about a quart or so) I figure the trees don't notice.

JHCC Posted July 15, 2020 Share Posted July 15, 2020 Neutralize any remaining acid with baking soda (add just until it stops foaming), dilute heavily (a quart of used vinegar in a gallon milk jug, top off with water), and disperse over a large area rather than pouring in one spot.

M.J.Lampert Posted November 17, 2020 Share Posted November 17, 2020 if i do three smaller pieces in a bit of vinegar can i reuse it for a few more if I add a small amount of fresh thanks before hand M.J.Lampert Link to comment Share on other sites More sharing options...
ThomasPowers Posted November 17, 2020 Share Posted November 17, 2020 Yes, No, or Maybe; depending. Use it till it stops working and then replace it with fresh. Link to comment Share on other sites More sharing options...
Frazer Posted November 17, 2020 Share Posted November 17, 2020 To test it's acidity, sprinkle a little baking soda in there. If there are lots of bubbles, it's good, if there are very few bubbles, replace with fresh stuff. You don't need much, you're not trying to neutralize it, just test it. Compare to fresh vinegar if you want a baseline. Link to comment Share on other sites More sharing options...

ThomasPowers Posted November 18, 2020 Share Posted November 18, 2020 To speed things up for small rusty items you can use an old crockpot for a heated vinegar solution---NOT TO BE REUSED FOR FOOD! Also don't do it inside as the fumes will rust everything in the shop. Link to comment Share on other sites More sharing options...
Slip36 Posted February 1, 2021 Share Posted February 1, 2021 Sorry to revive this, but how long should you leave your piece submerged in vinegar? Link to comment Share on other sites More sharing options...
Frazer Posted February 1, 2021 Share Posted February 1, 2021 Until the bubbles stop. It depends on the thickness of the galvanized layer, the strength of the vinegar etc. Sometimes a few hours, sometimes overnight. It's not an exact science.
