Onyx Hydrogen Peroxide 6% Pure Food Grade, Unstabilized and Additive Free - 20 Vols (1 Littre)

Great product! I purchase this regularly. Great for stain removal and, when diluted appropriately, brilliant for whitening teeth!

More than happy with product

It has many uses... I bought this for cleaning my teeth... I only use this once per week... My teeth are so white that I could blind an oncoming driver... Yep, I dip my toothbrush in it and it instantly removes coffee and nicotine... as always, be careful with chemicals around your body, but if you need something that works? This will do the job.

I have several uses for this. Removing blood stains from clothes, mould, stains & cleaning. I mix 1 to 10, works for me. Why dont I give it a 5 star, It has to be excellent/100%. This works well. removed stains on a wall, blood from clothing/sheets. Take care when using it.

I've been using it to stain off the yellowish colour of my teeth and works just as well as the whitening strips.I did make the mistake of using it a tad too much and my gums are multiple shades lighter, but thats my fault.You live and you learn to not mess with chemicals without thorough research.

Useful for cuts bites mouth wash all round antiseptic

Used it for removing a blood stain from carpet I’m not John wick but my dog did bleed on carpet not saying it will work for everyone like this just did on mine 🤷‍♂️

I fell for the Tik Tok hype and bought a bottle hoping that my teeth would miraculously start sparkling as white as Casper the Ghost. Unfortunately this was not the case, so ultimately I used it to clean and disinfect my bathroom (worked a treat in this capacity). Do not use as a teeth whitener, not for any length of time at any rate - my gums bled for two days straight.
