3. Oxalic acid is toxic. It should be diluted in warm water when used. Concentrated acid is easy to damage fiber.
4. The force should not be too strong when wiping, otherwise it will damage the fiber tissue and surface.
5. Potassium permanganate is a strong oxidant, which will destroy the color of the carpet and should be used with caution.
