Abstract: A concentrated aqueous solution for cleaning a component of an aftertreatment system of an engine system includes an organic acid at a concentration between 25% and 50% mass per volume of the concentrated aqueous solution, and a biological growth inhibitor at a concentration between 0.1% and 1% mass per volume of the concentrated aqueous solution. The concentrated aqueous solution also includes a surface tension modifier at a concentration between 0.1% and 25% volume per volume of the concentrated aqueous solution, and a foam controlling agent at a concentration between 0.01% and 15% volume per volume of the concentrated aqueous solution.
