Hello again,
I have both modules, they do work well togeather. The search and clean module is good for finding indivual issues, and allows you to click and clean any microdata issues.
For the issue to hand I would use the Json-LD microdata module. Once installed it automatically replaces all the affected partials, product pages etc etc. It then backs files that have been changed. Then you can edit options regarding the product page, open graph, breadcrum, etc and it also works with richsnippets.
So yeah, go for the Json-LD Microdata module.
