To remove sticky patch on uniforms due to mosquitoes patches

try this：Moisten a cotton ball or a clean, soft cloth with an appropriate amount of medical alcohol (75% or 95% concentration). Press the alcohol-soaked cotton ball onto the sticky residue and let it sit for a few minutes to allow the alcohol to fully penetrate and dissolve the adhesive. Once the adhesive has softened, gently wipe back and forth with the cotton ball to remove the residue. If necessary, you can gently scrape it off using a blunt tool (such as the edge of an old credit card). Finally, wipe the area clean with a cloth dampened with water and proceed with normal washing.
