Thank you for your question regarding the Delta In2ition® Two-in-One Shower and I am happy to assist you today.
This shower head cannot be disassembled to clean the internal components, although you should be able to unscrew the shower arm mount and soak the entire head in a solution of 50/50 white vinegar and warm water. For stubborn build up or debris, you may use a soft bristle toothbrush to clean the unit further.
I hope this information is helpful!
Please feel free to give us a call if we can assist you with anything else going forward at 800-345-3358.
