The Challenge
Acidity can accelerate
paper deterioration.
Acidic paper may become discolored, weak, and brittle over time. A deacidification project begins with condition, material, and media assessment because treatment can slow acid-driven deterioration but cannot reverse existing physical damage.
Discoloration
Yellowing and staining reduce readability and value.
Irreversible Loss
Advanced degradation can lead to permanent information loss.
When This Solution Is Needed
Consider deacidification when
collections show acid-related risk.
- Brittle, fragile, or easily torn pages
- Yellowing, discoloration, or foxing
- Low or unknown pH levels
- Collections selected for a pilot or phased program
- High-risk materials (wood pulp, acidic papers, newsprint)
- Mass collections requiring efficient treatment
Our Recommended Deacidification Workflow
Assess
Review paper, media, bindings, condition, and treatment objectives before testing.
Select
Choose mass, spray, or immersion deacidification according to material compatibility and workflow.
Prepare
Document, surface clean, test, and prepare suitable items for controlled treatment.
Treat
Apply the selected deacidification process under a documented project protocol.
Rinse (if needed)
Include rinsing only when the chosen aqueous treatment and material assessment require it.
Stabilize & Verify
Dry or condition materials appropriately, then document and verify the agreed treatment outcome.
