CRYSTAL DRY® EXTRA cleaning agent combines unique crystallizing polymers with effective detergent components, creating a perfect blend to emulsify embedded soils (both dry and oily) and encapsulate them for vacuum recovery. It will not cause re-soiling and will extend time between wet extractions to annually or longer in most situations. It has a neutral pH, no volatile organic compounds (VOCs), and is non-butyl. CRYSTAL DRY® cleaning agent is portion-controlled to provide consistent dilution for consistent cleaning as well as cost savings through waste elimination. CRYSTAL DRY ® EXTRA has received Green Seal Certification, WoolSafe Approval and the CRI Seal of Approval.
