KBS Klean is a powerful cleaning concentrate and can be diluted 10-parts hot water to 1-part KBS Klean for most cleaning applications, but it is BEST to use KBS Klean full strength when cleaning the inside of a tank as tanks typically require the maximum cleaning power available. Full strength for KBS Klean is 1-part hot Water and 1-part KBS Klean and that is what we recommend using when cleaning the inside of a tank.
