Dog odour, spoiled food, smoke and dampness are different problems and cannot be solved by one guaranteed process.

AVP first identifies and removes accessible sources, then cleans affected materials and ventilation areas.

Neutralisation can be an additional stage after drying. It does not replace repair of a leak or removal of contaminated material.

Results depend on access and whether the source recurs, so the blanket no-return guarantee in the original article is not used as a current promise.
