Hot pressing: If the pattern of offset printing is not serious, you can hot press the pattern on the T-shirt with an iron or hot press. It should be noted that the temperature and time must be controlled to avoid scalding the T-shirt or further damaging the pattern.

Banana oil or acetone solution: Dip a pure white toothbrush in banana oil or acetone solution, and then gently brush the offset printing pattern on the T-shirt. Then use absorbent paper towels to absorb the offset printing, and then dry the T-shirt.
