A method includes applying an infiltration coating (122) on a thermal barrier coating (106) of an article (510, 702). The infiltration coating (122) infiltrates at least some pores (124) of the thermal barrier coating (106). The infiltration coating (122) decomposes within the at least some pores (124) of the thermal barrier coating (106) to coat a portion of the at least some pores (124) of the thermal barrier coating (106). The infiltration coating (122) reduces a porosity of the thermal barrier coating (106). The method also includes applying a reactive phase spray formulation coating (102) on the thermal barrier coating (106). The reactive phase spray formulation coating (102) reacts with dust deposits (104) on the thermal barrier coating (106).
