For me it HCl, it work well but if that fails it’s sulphuric acid and if that doesn’t do the trick I use piranha solution. (Btw those potassium permanent stains HCL for the win)
I think turning them into insoluble salts & precipitate out as dry powders work the best. It's extremely important not to just throw solutions of heavy metals down the drain or the toilet. Keeping the dry powder waste is the safest, least-toxic, & most environmentally friendly way to dispose Heavy Metals.
You shouldn't use it routinely, it is very corrosive and rather dangerous. It is however useful for some glassware, like Buechner funnel filters, and other sintered filters, i.e. in chromatography columns.
I would be more botheted about breathing in the solvent vapours. For a short exposure time they are all relatively safe but if you use the cleaners every day then you'd better have a good ventilation. Or at least use a gas mask if it is completely impossible.
I have a very similar problem, I don't know whether organic/inorganic either. Will be trying the more aggressive chemicals. A Liebig by comparison is easy :)
Hi, have you find the solution for this? I do have similar problem. We used to clean it with crom-sulphuric acid, but seems like never stay clean for long time
Hi, my name is Potassium Hydroxide and I'm an alcoholic...
I am carboxalic acid let’s meet and make an ester together
Swear 😂

helps dispose the bodies
Now that how you clean a bong.
99.9% isopropyl alcohol as the solvent and normal table salt as abrasive, then just shake it up
How to I get rid of acid mixed with dissolved with organic material without my hands falling off.
Nice..👍
Our lab uses heavy metal ions, which detergent should I use to remove those?? Is water enough to dissolve the metal ions??

Can we use methanol for washing glassware
It evaporates well, although I'd still wear appropriate gloves as needed. Can be 1 part of a full cleaning routine
Thank You ! 🙂👍
Thx for tips 🎉
no gloves, nail polish?
Fashion first. Safety second.
Same thought. After Methanol with bare hands the 10% NaOH with gloves.
Seems tedious.
GRRROWL WHOS BADDER ? CHROMIC ACID OR PIRANHA SOLUTION! WHO WINS THE BELT!??
This drives me crazy, where is the PPE when you are washing stuff?! And methanol? WTF!
Don't you know? Once the experiment is done the chemicals are no longer harmful.
You know how much methanol costs! No! Windex!

How to clean autoclave ..
AUTOCLAVE FULLY SALT CONTANTS
Any one tell ??
very thak you madam for your help
Seriously? Methanol on hand? Isn't this supposed to be toxic on skin contact?
hehe, toxic? Not for a short contact
It's not that toxic and evaporates quickly. Note that methanol is normal part of human metabolism. Only higher concentrations are dangerous.
Libor Tinka it depends on how much you're cleaning but generally it's advised to not handle it without PPO

Hi Nyron
(cringing while she uses methanol without gloves)
How to clean a spiral condenser like graham?
I have a very similar problem, I don't know whether organic/inorganic either. Will be trying the more aggressive chemicals. A Liebig by comparison is easy :)

Lab women are so hot. Come to think of it, so are non-lab women.
:D
Yeah....Ginger girl is kinda hot!
Called PIRANHA SOLUTION! GRRRRRHH!
