@Random Experiments Int. - Experiments and syntheses great tip! just for others reading that may ask: nylon, polyester, cotton, lycra, wool... Would those fabrics/materials be affected by HCl/citric acid? what about dyes in those fabrics. Are any dyes specifically sensitive? Thank you again. Rob.
Excellent - so many questions blown away by this simple and clear video. Thank you. However I have one remaining question: are there any proven methods of precipitating hardness by dripping on to a gravel substrate?
I remember trying to find out what made up the yellow stains from antiperspirant, but couldn't get any solid answers. It's kind of gummy and reminiscent of lime soap (or soap scum) so I was thinking maybe something like that. The Al and Zr ions forming a soap with free fatty acids directly/indirectly from the skin or some type of oil-producing skin gland. It'd be interesting to see if you could recreate the compound, and then see how to re-dissolve it (EDTA solution + something?)
This was actually interesting to me personally, because I actually did a few experiments on how to remove the aluminium stains. I was pretty sure, that acid is the solution and that it had to be an aluminium salt with an organic compound as the anion. So, I treated my shirts with hydrochloric acid and citric acid. I was wondering if the HCl would destroy the fabric, but strongly diluted it worked very well and quick and even after 10 years the shirts are fine. Today, I treat my shirts somewhat regularly with a solution of citric acid in water for 1 or 2 days, rinse them and then put them in the washing machine with my other clothes. It usually removes most/all of the stains. Aluminium free alternatives have become better within the last years, though. So, I switch between them.

What are the effects of drinking water from a kettle with lots of limescale buildup
Really helpful and knowledgeable experiment.
Great work, i think you can make a video regarding EDTA and chelation reactions.
Thanks for the video. That was a great explanation and demonstration.

How does it effect health?
Hello sir. Can You make video on synthesis of valerophenone.plsszz
Thank u so much bro. When I watchingur video at first. I subscribed it. Because I will learn chemical thank u bro🐭
No more videos :( ?
Why is it the only good chemistry channel on YT that seems to remain alive is one that tends to make tar more than anything else?
why are you not uploading videos
