If scouring powder and pad don't work, you will have to buy new beakers. Heavy metal silicates are absolutely insoluble - except for hydrofluoric acid which would destroy the glass, too. That's why I always used old canning jars for this experiment. Don't pour the sodium silicate solution down the drain, because - depending on what you pour in next - the formed silica can block it. Better bring it to the collection point for hazardous waste. Nice structure! Unfortunately it often collapses, when the liquid is poured off. This can be avoided If you convert the top of the solution into a silica plate by adding a few ml of dilute HCl onto it, so that the grown dentrits can stuck at it, which gives them more stability. You can make your garden more colorful if you use salts from other metals, too, for example ferric chloride, ferrous sulfate, lead nitrate, cobalt chloride, manganese sulfate and ferri-/ferrocyanide.
You could try putting the beakers into an ultrasonic cleaner. I often clean my glassware this way and it works for most things (for easy things it's very quick, too).
@Amateur Chemistry 2:48 That´s in fact silicic acid that precipitated out of solution as you acidified it with acetic and citric acids, since silicic acid is a very weak acid. It´s weak enough for even carbon dioxide to precipitate it from sodium silicate solutions.
@Amateur Chemistry 7:03 Copper(II) silicate can be cleaned from the beakers by using hydrochloric acid which will form a solution of copper(II) chloride and a precipitate of silicic acid which should be loose from the glassware.
I think a hot solution of NaOH would dissolve the silicate stains, maybe similar in strength to what you made the sodium silicate, so as not to etch the glass _too_ badly.
Easy way for trying to get rid of silicate stains Dump potassium permanganate crystals in it, it will destroy the stains and your garden will become barren as well
you should pull the 14 year old from your channel description. it increases the likelihood of a strike and might also prevent you from getting monetized
@@Amateur.Chemistry chloroform is not the issue. youtube doesn´t really care about that but it does care very much about your age especially with your type of content

Thanks! After all this time some of my beakers are still stained, and now I will finally be able to clean tham :)
2:55 Silicagel. Again.
More precisely, at first it is unstable silicic acid
Did you capture any time lapse footage of the crystals growing?

would dichromate work?
good video! I subscribed.
where are u from?
Thanks! I am from Poland
Wasnt there a chem kit back in the day for these. I vaguely remember
There was one but it was phased out because kids ate the copper sulfate.

I will detete it and the hmtd video as soom as i will apply for monetization. I also hope that youtube wont get mad about the chloroform.

@@THYZOID Thanks!
i think it is
h2si03
I think it probably formed H2SiO3 as an intermediate in forming a silicate polymer
first hah seems nice
