Cleaning Validation in Formulation

Please clarify me on the MACO.
Is it For one stage or Combined for Total Cleaning Validation.
(Example: MACO is 2000 mg, IS it Calculated per euipiment or sum of all equipment used in formulation)

Dear sallunaaz,

you can calculate the MACO per square area.
Then on the basis of this MACO per square area you can validate the cleaning procedure separately for equipment / for each stage / for complete product.
