Can Hardener Pouches Be Used with All Purpose Formulations?  

Yes. However, the hardener is optional and packets are sold separately.

Rx Destroyer Liquid line of products includes enough hardener packets for each bottle in the case.

When using hardener packets with All-Purpose formula, ensure that bottle contains at least 10% liquid. This allows hardener packets to fully dissolve, allowing disposed medication contents to achieve optimal hardened state.
