Underwear, summer clothes, bedding and other intimate clothing, as well as cotton, linen, and blended clothing, are prone to residue. Try not to use softener. agent. It is also not recommended for children, the elderly, pregnant women, lactating women and those with allergies.
If it must be used, the dosage should be reduced as much as possible, rinsed at least 2 to 3 times during washing, and fully dried after washing to make the agent evaporate as quickly as possible.
