Depends siguro kung ano ung mandated maintenance wash nung coating product na gamit nung shop.
Actually it depends din kung ano ung "maintenance wash" ng shops. For me kasi ang maintenance wash is, wash the car using a pH neutral soap and then Si02 spray sealant as a drying aid. Ginagawa ko ito once in 2 weeks para ma-retain ung depth and gloss.
Pag decontamination wash naman, mas thorough ito. Gagamitan ng coating safe iron remover and tar remover if needed. This probably 2x a year BUT again only if needed.
