I recently bought a used boat that has had Cetol applied to its teak
(companionway boards, handrails, helmsman seat, etc.). The Cetol has not been
kept up and needs to be refinished.

Is it best to sand off all the old stuff or remove it with a chemical removal
product?

Unless the teak under it black, you only need to sand and re-apply two
coats to bring it back. If the wood has blackened you'll need to strip
it same as you would varnish and then sand before using Cetol again or
anything else.
