  In addition to exposure to heat and UV light (as highlighted in the linked question):
  
  * Temperature fluctuations can cause the rubber to expand and contract which will weaken the rubber.
  * Certain cleaning solvents used on the model may cause damage to the material, it might be best to remove the rubber bands when cleaning models.
  
  There are specific rubber coatings available that can help maintain the elasticity and flexibility of rubber bands. One particular product that I am familiar with for rubber band magic is '[Elastraflex](https://www.vanishingincmagic.com/magic-accessories/elastraflex-50-oz-bottle/)' which is quite pricey and may not necessarily work for rubber bands manufactured by LEGO.
  
  Unfortunately unlike LEGO bricks, rubber bands have a much shorter lifespan when in use or in storage due to the nature of their material.
  
  It may be more economical to buy a pack of non-LEGO rubber bands that have similar properties to LEGO-made bands and storing unused bands in sealed plastic bags.
