Yes, hot glue does wash off the fabric and can be easily removed with soap and water. Hot glue is an adhesive used in the making of costumes and other craft projects. Hot glue usually starts out as semi-solid before it sticks to wet surfaces like fabric. Hot glue also often has a strong scent that fades as it dries, but this too can be easily washed off with soap and warm water just as the adhesive is removed from fabrics.
