1. Method 1: Drop banana oil on the glue stain and keep stirring with an old toothbrush. When the glue stains become soft and fall off, rinse them with clear water and brush them repeatedly until they are clean. Stick absorbent cloth on the back of the clothes with glue marks, then coat some white vinegar on the glue marks, and finally scrub them with cotton dipped in water.

2. Method 2: Use insulating oil and pour the insulating oil in the transformer on the table. The 502 glue will soon become soft and can be wiped off quickly.

3. Method 3: 502 glue is a kind of resin glue, as long as you use an organic solvent that dissolves resin, such as acetone. However, inhalation of acetone is toxic, so attention should be paid to its use. You can stuff the sticky part into the bottle. It is said that the glue will fall off if it is frozen in the refrigerator. You can try it first.

4. Method 4: Stick 502 glue on a small area and soak it in hot water. If 502 glue is stuck on a large area and acetone is coated, it can be removed in about 5 ~ 10 minutes.

5. Method 5: recommend acetone, gasoline, sesame oil, etc. Pour some insulating oil into your hands in the transformer, and the 502 glue will soon become soft and easy to rub off.
