mineral baths

How can I fix my shower faucet instead of me?
at the top of my bathtub faucet is a thing to pull turn tap water. I think it is a mineral that forms there (we have an old house) and now I can not pull up to activate the shower. water leaves only take a bath tap – no showers! This is a big problem is that someone could explain if I could inject something to prevent accumulation or I take it all apart … Thank you in advance!
Do not use a pipe wrench for valve replacement or repair to avoid scratches on the surface of chromium using an adjustable wrench. Use warm vinegar to dissolve the deposit mineral. Clean and lubricate moving parts. Good luck
