Many veterinarians believe that although the addition of antimicrobials to lavage solutions is beneficial, much of the benefit is the lavage action itself.

Copious lavage of a contaminated wound with water (more specifically, sterile physiologic saline or another sterile balanced solution) alone is of great benefit.
It has also been demonstrated that regardless of lavage solution used, lavages are more effective at flushing away bacteria and contaminants if applied by pressure.

A pressure of at least 7 psi is desired.

This pressure can be generated by a plastic spray bottle on the "stream setting," a 60 ml syringe with an 18 gauge needle on the end, or a dental "water-pik." In conjunction with lavage, mechanical debridement is beneficial in aiding the removal of bacteria and foreign material.

Remember: The answer to pollution is dilution.
