A cap device and method for covering openings of different sizes on a structure, such as for example smoking apparatus, are provided. The cap device comprises a cap having at least one elastic portion or area that is stretchable over an opening of the smoking apparatus to form a seal over the apparatus opening, which for smoking devices, can seal the opening to contain a cleaning solution within the smoking apparatus. The cap has grasping portions for a user to hold it simultaneously while stretching it over an opening on a smoking device. The cap device is easily removable when the cleaning is completed, and the opening of the structure no longer needs to be covered.
