The steps are as follows:

1. Separate the seal from the handle, fold it into many layers with facial tissue, place it on the front of the seal, add the plastic cover of the seal, and use a large clip Clip it on and change the tissue once a day to absorb oil. Use until there is no yellow transparent oil on the tissue paper. For photosensitive seals, drip the seal oil from the area with words on the front, cover it evenly with a paper clip until the oil penetrates, and wipe off the excess ink with a tissue.

2. Press the paper towel on the surface of the photosensitive seal, use your palm to press it and suck out the ink inside the seal. Suction it a few times. Don’t be afraid of trouble. The oil will not cover any traces. Use it again at this time. Wipe the sealing surface twice more with a paper towel to wipe away the impurities and paper scraps on the surface. Then turn the photosensitive seal upside down, apply special oil for the photosensitive seal on the text, and place it upside down until the sealing oil is completely penetrated.
