Oxalic acid is the reason why you DO NOT eat rhubarb leaves. However, one thing I learned in a mis-spent scientific career is that it does work quite well at low concentrations to deal with iron stains on fabric. In the case of dyed fabric then check for interactions first.

I once sent my mum to get some from the chemist, warning her that she might have to sign the poisons register and she came back with a commercial product containing Hydrofluoric acid with very inadequate safety instructions.  I know which I would sooner risk! I used the commercial product with the precautions we took in the lab because I didn't fancy hours of severe nerve pain if some got onto my skin -  one of the technicians described it when there was a pinhole in his gloves on a hot day and he didn't realise that some dilute acid had got in contact with his skin.

Oh wow, I think I'd rather be shot than get a drop of HF on my skin. One of the reasons I have this public safety job is because the company I work for uses hydrofluoric, hydrochloric, sulfuric, and nitric acids in production. My hazmat certifications are largely because the storage and neutralization tanks for those four acids are right next to liquid oxygen, liquid hydrogen, and liquid nitrogen tanks. If there was ever a fire in the chemical storage area... I shudder to think of how bad it would be for anyone within a few miles downwind.

There was an etching solution in use at the time called Tuckers etch which as I recall was conc sulphuric, fuming nitric (or the other way round), picric and HF, used boiling!

In case of HF exposure we had capsules of calcium gluconate available with instructions to take an appropriate number to the A&E 5 min walk away and INSIST it was injected immediately under the contact area. If you swallowed it then you could try to drink milk before you went to A&E, eyes then you contacted the Eye Hospital via 999. In all cases take the capsules with you just in case. Posters giving all sorts of treatments for chemical exposures were prominent, we also had a lab with enough cyanide to poison the whole city. Still, I survived it.

My mum worked on one of the original polythene plants, high temp & pressure exothermic process controlled (it was WW2) by girls operating a pressure valve. The reactor building had a hinged roof for faster repair since every so often someone turned the control the wrong way. In between sessions on the controls she used all sorts of toxic hydrocarbons on what they described as 'gas testing' with minimal protection. COSHH eat your heart out.

Glad you all had a smile over the horrors of the scientific past. COSHH applied sensibly was a good idea. But some of the implementation left something to be desired.

One chemical supplier decided to fulfill their obligation to provide hazard data with every chemical by providing regular customers with a handbook - obviously put together with lots of copy & paste judging by the advice on this substance.

Contact with eyes - wash with water
Inhalation - remove from contact, check breathing, seek medical advice
Ingestion - drink water, seek medical advice
Contact with skin - wash with water
[Some editorial simplification but it was over 20 years ago.]

The substance in question was distilled water!  ???
