A chastity cage, penis cage, or chastity tube are common names for types of popular chastity devices for men. They are almost solely used as sex toys and in BDSM play, and if a man becomes sexually aroused, it cages his penis by making an erection uncomfortable or impossible. It also restricts oral sex with the wearer's genitalia, masturbation, and other forms of sexual activity.

To be secure and protect the genitalia, a chastity cage needs to be appropriately sized, fitted, and adjusted. The two most significant changes can be made to the ring size and spacing. If a ring is too tight, blood flow will be cut off, and if it is too loose, it won't be stable. Allergies are associated with the types of chastity devices worn, and it is necessary to know what works best to reduce metal allergies and metal toxicity.

Long-term male chastity requires cleaning, but doing so constantly can be exhausting. There are efficient ways to clean a steel chastity cage without having to remove it all the time. It is easy to clean steel cages that provide some access without removing them.

Considering your lifestyle, penis type and size, your habits, and your level of activity can help you choose the right cage and keep a healthy cleaning schedule. As penis size and shape vary, it is crucial to understand exactly how the style of the device will affect you personally.

• Antibacterial soap
  A mild or gentle antibacterial soap is less likely to irritate delicate skin. Avoid using soaps that do not soothe your skin or will react to the type of cage used. 
• Cotton swabs and Pipe cleaners
  Cotton swabs that are both soft and strong are excellent for getting into all the holes. Cotton swabs can be used to lather and scrub the interior and base ring of a steel chastity cage after becoming soaked slightly using water and a small amount of soap.
  
  Also, pipe cleaners are effective for cleaning the area surrounding the base ring, but exercise caution as the wire inside the cleaners might injure the wearer.

• Water gun or a water bottle with a sprayer
  To ensure that all the soap and any dirt are washed out, you will need to find a means to create water pressure. It's unlikely that standing in the shower or submerging the cage will be effective. Use a small water gun or, if you don't have one, a shower sprayer.
• A blow dryer
  The most important part is probably a source of forced air which might dry the cage as well as its insides. Extra wetness should be avoided. For efficient cleaning, make sure the cage and its contents are dry. If not, you can discover that cleaning is ineffective.
  
  

• Apply soap to a cotton swab and scrub the cage from all sides, shoving it inside and outside. For tight spots, use a folded pipe cleaner.

• To scrub the inside of the base ring between the steel and the skin, loop a lathered pipe cleaner around it so that you can grip it from either end and pull it back and forth.

• In the shower, fill a tiny super soaker with hot water, then spray it through the cage. Shower as usual, but be careful to wash the region around the groin.

• After leaving the shower, use a source of forced air to completely dry the cage and its contents. Use a moisturizer that's best for your skin around the base ring.

Cleaning your chastity device and all of its contents daily is important, especially if you've been physically active. Any moisture is harmful because it attracts bacteria to the penis. The cage must be removed for cleaning at least once or twice a month - depending on what works for you. To be safe, it is critical to check for potential problems, but it is advisable to keep it clean all the time.
