Taking care of your stand.
Acrylic is beautiful, but can also be sensitive to certain cleaning agents. Never use any product that contains ammonia. It can reduce the life of your plastic, and even crack your plastic due to a chemical reaction.

Here are some things that we use here.

• Pretty much any eyeglass lens cleaner.
  
• Plain water & a little dish washing soap like liquid Dawn.  Even your $1 store generic works great. Mix it in a spray bottle.
  
• A lint free cloth.
