The solvent of 2502 glue is acetone (but inhalation of acetone is toxic, so pay attention to the use method. ), make sure that the clothes stained with 502 glue do not contain acetate fiber before using acetone. When removing stains, it is best to turn the clothes upside down and pad them with absorbent materials (clean towels, cloth or toilet paper, etc. ) under the stain. Use a dropper to drop acetone around the stain and gradually dissolve it from outside to inside. You can also spread a layer of cloth on it and gently squeeze it to help dissolve it. Then replace the adsorption material and repeat the above operations until the dissolution is completed. In addition, acetone may affect the color of some fabrics, so it needs to be tested in the back corner before use. If 502 glue is applied to the blended fabric containing acetate fiber, the fabric will become thinner after removal. If the fabric is all-acetate fabric, the fibers in the stain will dissolve into irreparable holes.
