Repeat the process as needed until the stain fades completely.

Alternatively, dissolve 30g of citric acid in 300ml of boiling water and use this solution to wash the stain.

Apply oxygen-based stain removers like Amway Pre-wash, Bagi, Cotico, Vanish Oxi, Udalix, or Lion to the stain and leave for 10-15 minutes.

Use an oxygen-based stain remover stick (such as Udalix, Brandfree, or Faberlic) by dipping the tip in boiling water to create a foam, then apply it to the stain.

Apply Ringuva or Sodasan gall soap or spray to the stain and work it in with a soft-bristled brush.

Use Pro-Brite Axel 3 Rust remover, which is effective against rust, potassium permanganate, and blood stains.

- Wash items with regular detergent at a high temperature after treatment, ensuring you check the garment's care label first as high heat is not suitable for all fabrics. - Be aware that if potassium permanganate has deeply burned the fabric fibers, the damage may be permanent. - Consider covering any remaining marks with a thermal patch or by drawing over the area with fabric markers.
