- This is just a quick tip for removing the metal spoon stains from your coffee cups. Careful with anything bleach; you NEVER want to mix it with ammonia.

You can remove coffee, tea, and spoon stains from cups with salt pretty easily. Just throw some water in the cup pour it out and then put some salt in the cup. It makes a little paste and when you use your hand to scrub it around it all comes off like magic.
Bleach, which is sodium hypochlorite, may also be viewed as the sodium salt of hipochlorous acid, thus if you add hydrogen peroxid to bleach you will get the following reaction: H2O2 + NaOCl → NaCl + H2O + O2 . Needless to say this reaction other than being rather violent, produces a lot of oxigen which is, as you can imagine, a stong oxidizer! I'm a dentist and I use those two substances for a variety of uses including (believe it or not) cleaning the inside of a root canal from any residual organic material before "sealing it up". (sorry for my English, I'm italian)
You should probably add a disclaimer to wear gloves or something...
Thank you! It works great. Sorry, vinegar - baking soda - elbow grease crowd (you can usually even skip vinegar and soda), kind of got tired of you.
nice quick tip.
I always stir my coffee with a plastic spoon. Problem solved.
Thank you for this tip! But does peroxide make a real difference compared to ordinary water? Me, I always scrubbed my cups with Comet or such stuff with a few drops of water, I've never fancied to add peroxide. Now, I've tried to clean two halves of my scratched cup by both methods, and I see no difference. But you, obviously, have experimented more. Did you find that peroxide improved the cleaning power of Comet?
I have had some luck simply wetting the inside of the cup, sprinkling the inside with table salt, and scrubbing away just like you did. It works fairly well, actually. It's probably easier on one's skin.
Just found this video, restored a vintage cup from 1985, thank you so much! Everybody in the world has comet and hydrogen peroxide in their closet. I wore a glove and did this outside just in case LOL
I'd like to know what the metal is that is in my cups. It seems to come off with acid, and that scares me to think what I'm drinking when I make tea with lemon.
Hydrogen peroxide is a strong oxidizer, and essentially turns the metal into rust that is then easily scrubbed away. You can make it even more powerfull with the addition of an acid to start the oxidation proscess.
I was going to mention Applied Science and then you brought his channel up too. In his video he used a solution called piranha or something, I believe it involved H2O2 and sulphuric acid or something along those lines. I wanted to try cleaning some of my bowls but I didn't have the acid, but now that I know it works with more household chemicals I'll give it a shot. Thanks!
Erasers work to
I use white vinegar and a fresh kitchen sponge scouring pad.
Cool! That'll probably work for the tool marks I get layin' tile.
Use a Mr. clean sponge.
You get a like as your speaking voice or presentation is pleasant and a like for omission of a 2 second music clip, repeating throughout the video...
EWG gives Comet an F. I use sodium percarbonate (non-chlorine oxygen bleach) solution.
Video idea, do a comparison with a mr clean magic eraser then maybe explain how those white cubes work their voodoo would be interesting from a scientific view!
what are your spoons made out of? such staining never happened to me with stainless steel utensils. I know alumin(i)um can leave marks similar to lead but i haven't seen aluminum utensils for a long time since aluminum has been considered not the greatest material for contact with food
