4 The Birds can attract dirt because it is so sticky. According to the 4 The Birds product label:
Repellent can be removed from interior surfaces, such as metal
beams, wood, laminates and painted surfaces, with "EATON'S"® Bird Repellent
Remover or with mineral spirits. Repellent can be removed from sealed concrete, tile
or stone surfaces by hosing with water if this is done within a very short time after the
area was coated. Application equipment should be cleaned with "EATON'S"® Bird
