How to permanently delete product type options

[RoyalCaffe]

I need to complete delete some product types (some is mistake) so no other worker will have the option to choose it again

Go to Products > Collections (if using collections for types).

Find the product type and delete it.

If using tags or custom fields, remove those from the database.
