    This guy used Whink without gloves (overlooked the skull and cross bones I guess).

    https://www.doctorslounge.com/dermat...pic-46036.html

    This alternative method looks to work much faster and removes more quartz. It has its own risks. I think I might try this next time instead of Whink.

    believe it or not I've been trying to be on TNET less.

    Yes it is exactly what I do.

    You can barely tell theres gold in most of my finds when they come out of the ground

    i use heat and shock. Muriatic acid , or Whink rust remover.

    Vinegar, coca cola, and even hot sauce.

    dental picks and a long deck screw as a mini auger popper.

    allof this allows me to let the speci. do the talking based on what coes off

    the muriatic is slow controlable and easy to neutralize. whink reguires more caution.

    I've never hurt myself or " ruined a piece"

    there is also a glass etch product available I was given some by another digger.

    I haven't used it since Claydiggins turned me onto Whink

ID:	1671080a before and after of just a basic clean up.. if you have continuity in a piece and know a lump is all the way through in even a week of acid-neutralze-pick tools repeat you can get rid of most or all of the quartz.. calcite is a little longer.

    Some host rock like slate and granodiorite just melts away in one or two soaks or gets soft enough to brush off.

    Man I sure did miss this thread..lol

    You guys are all gonna DIEEEEE...

    From reading the internet..100% effective to making the sky fall..


    I use baking soda and water to neutralize.. I soak the pieces in a solution with so much there's still powder in the bottom of the cup.

    when I use whink I also run a hose into the container (Post neutralize bath) at flow enough to exchange about a tablespoon of whater a minute.. for several hours

    theres grass growing there so...there is that..

    With muriatic I let it sit until the bubbles stop coming out of the matrix..take piece out of soda water, let the piece sit.. if it leaches out yellow after a few hours ..it goes in the soda water longer..then a dilution rinse..


    I handle the pieces quite a bit within minutes of rinse..thats when I'm using the pick a toothbrush and a spray bottle... I've had water splashed on my face from the spay...I don't wear gloves.

    I try to remeber to wear glasses for the flying mini quartz shrapnel.

    THERE IS A SAFE AND EASY WAY TO ETCH WITH HYDROFLUORIC ACID.

    I WILL EXPLAIN IN A MINUTE, BUT KNOW THAT EVEN FUMES FROM HYDROFLUORIC ACID ARE HORRIBLE.

    OK. Scary stuff aside, go to a stained glass hobby shop and buy a bottle of the hydrofluoric acid stuff they sell to etch glass. It's "buffered" in a way to render it mostly harmless. This will probably do what you want. If you are not trying to etch, but instead dissolve quartz etc, that is another matter entirely. Leave it to the pros.

    “Wink requires more caution”
    10-4 on that. Safety glasses and gloves.
    There is no denying that it consists of 2.5% - 3% HF which causes permanent damage to your eyes and is lethal if swallowed. It will enter your system just the same as stronger HF.

    It’s easily avoided, but nothing to be calvalier about.

    actually thats not true, at least in certain concentrations. I can buy it for glass etching and have used it in the past, but I too try stay far far away form that stuff.

    thats just a short two soak two neutralize wash.

    the one thing the acid does is help to weaken the matrix for easier mechanical material removal.

    If you have a piece that is mainly gold and soak it longer the matrix will eventually come almost all the way off on its own but with such weak acids it takes a while.

    Not being cavalier i'm being an experienced smart ass.

    Whink is not HFL it is a solution containing a % of. Pouring on like hand sanitizer is probably not a good idea though.

    If you read the bottle it is used on clothes.. guess how you neutralize a towel you cleaned with whink?

    You put it in the washing machine...with othwer clothes.


    I know it may be a mistake but, I'm assuming that anyone who is going to be using these diluted acids wil still use common sense

    My point was thaat after being properly neutralized the pieces are very safe to handle.

    Study up on how to handle the acid. and what and how to neutralize. Proper disposal of used solution.

    Proper work environment.

    the fact is a slight breeze and the tailgate of your truck are perfectly safe.

    Don't stick your face over the containers to look. The whink I use comes in a safety squeeze no splash bottle. Muriatic is easy to pour. when I'm transferring small amounts in small containers i use tongs... cause if it gets on a glove i have to take those gloves off... with my hands..

    I use long tweezers to pull out pieces that I want to neutralize and work on.. while leaving others to soak longer.

    Keep in mind this is etching.. so its a small layer at a time...

    I have no desire to work with a stronger acid. Caution is required with what I use.. but, it is in no way the same as working with the stronger formulas available.

    I've had hours of mandatory chemical safety and MSDS training. I've used chemicals in commercial dishwashers that were much more dangerous than Whink rust remover.

    I know nothing about acids for gold and quartz but did have a fun experience with muriatic. I was building an office complex and had half of it occupied. Had my tile guys to come in and clean the floors. We had high humidity and the muriatic acid caused a visible fog and had to evacuate the building. Humidity was the culprit and it was not a good day to be the all knowing superintendent. Use common sense better safe than sorry right?

    Just for the record, Whink is made by taking concentrated HF and diluting it with water to the point of being 3% HF Acid. Then a chemical is added to give it a bitter taste.

    That’s all it is ..3% HF that tastes bad. Nothing magical.

    I have seen MSDS sheets showing it as high as 8% HF.

    Let’s just say there is a hole in your glove and some is spilled on your fingernail.
    You assume it’s just sweaty hands from the gloves.
    You forget to rinse immediately.
    You will not notice any I’ll effects until the next day (due to it being diluted to 3%).
    Your fingers will feel like they were smashed with a hammer and your fingernail will need to be cut off for treatment.

    I believe that to be the reality.

    Knowing this means you avoid gloves with holes in them, and know how to neautralize the acid.
    You wear eye protection so as to avoid some sort of permenant damage.

    Other chemicals are bad, but they don’t quietly creep through your skin and mess with your bones.
    Usually it’s a burn that you quickly notice and the chemical is rinsed off the surface of the skin. The skin heals and your good to go.

    Not like it’s the end of the world. I see lots of old guys with fingernails that look like this.

    This was from exposure to a rust remover product that was made for carpet.
    According the source.

    According to the expert...”Ive had it on my hands before and just washed it off and it's fine, and fumes seem to be minimal. Just rinse well!! You don't want to taste this stuff on your smoke“

    “My husband and I used Whink on a broken glass stem that we had been using for months to do hot rails, and it was really looking bad with burned/melted meth stuck on the end like tar. Even that piece got totally clean and looked brand new. I wish I took a before and after pic”

    How funny!

    already knowing this is why its the strongest hfl I would use.

    hating gloves for the fact that they actually mess with the ability to grasp and handle well is why I use tongs.

    also the wink I buy is in a no splash dispenser.

    I would never put my self in a situation that so much HFL would even get on my gloves.
