If potassium permanganate accidentally drops on your hands, the cuticle will turn red or yellow. This situation can't be washed away, but over time, the skin's own metabolism will make this color gradually disappear.
After the skin is dyed by potassium permanganate, it can be washed with vitamin C. If the concentration of potassium permanganate is relatively high, the skin will be seriously dyed and appear purple-black. Rinsing with clean water is difficult to remove. It is necessary to dissolve vitamin C tablets with a small amount of warm water.
Then apply a cotton swab to the dyed skin and remove it several times. If you don't have vitamin C tablets, you can buy lemons and scrub them off.
When using potassium permanganate at ordinary times, we should pay attention to the slow dissolution rate of potassium permanganate. If it doesn't dissolve, you can shake the basin or cup instead of touching it directly with your hands, otherwise there will be skin dyeing problems.
Cleaning method of potassium permanganate falling on ceramic tile;
1. Add a little pear juice to the polluted place. There is vc in the juice. Use the redox reaction of potassium permanganate and VC to see if it can decolorize.
2. It can also be soaked in citric acid or 2% oxalic acid aqueous solution to remove stains through chemical reaction.
3. The key is the maintenance of the tile itself. Sealing the pores on the surface of ceramic tile to prevent colored pollutants from infiltrating can make ceramic tile not dirty. At present, there is a new patented technology product that can seal the pores on the surface of ceramic tiles. You can try.
