There is no dirt that the Blood of Christ can not wash clean.
Titus 3:3-6
3 For we ourselves also were sometimes foolish, disobedient, deceived, serving divers lusts and pleasures, living in malice and envy, hateful, and hating one another.
4 But after that the kindness and love of God our Saviour toward man appeared,
5 Not by works of righteousness which we have done, but according to His mercy He saved us, by the washing of regeneration, and renewing of the Holy Ghost;
6 Which He shed on us abundantly through Jesus Christ our Saviour. . .
