Returnable bottle washing and label removal guide
Returned bottles need a different process from clean new bottles: label condition, adhesive, residue, bottle damage and proof of the final wash all matter.
Map the returnable-bottle sequence
A returnable bottle process often needs sorting, inspection, de-labelling, pre-rinse or wash, final washing, dry-off and rejection points. The correct sequence depends on label material, adhesive, bottle damage, contamination level and whether the bottle is safe to feed into the next process.
| Stage | What to check | Possible route |
|---|---|---|
| Initial inspection | Cracks, chips, foreign objects, heavy contamination and wrong bottles | Manual or automated rejection before washing |
| Label removal | Label material, adhesive, bottle diameter and remaining glue | LU-BLR18 or project-specific de-labelling review |
| Final wash | Internal residue, outside finish, residual adhesive and rinse result | Automatic, rotary or wash-and-dry route depending on output |
Label removal before bottle washing
Label-removal performance is affected by bottle diameter, label coverage, adhesive type, paper or film material and whether the bottle is wet, dry or damaged. The LU-BLR18 route is included on this site because returned-bottle preparation often needs de-labelling before final washing.
- Send labelled bottle samples or photos
- Confirm bottle opening and body diameter
- Record target output and rejection criteria
- Check whether adhesive remains after label removal
Avoid confusing reuse washing with pre-fill rinsing
Pre-fill rinsing is usually aimed at clean new containers. Returnable-bottle washing is a broader process because residue, label removal, water quality, drain load and validation evidence can all affect the decision. Where a rinser-only route is more appropriate, compare with the separate bottle rinser site rather than forcing a washing solution.

Buyer questions
Do returned bottles always need label removal?
No. It depends on the label material, adhesive, bottle condition and final presentation requirement. Where labels remain, de-labelling may be needed before final washing.
What should a brewery or winery send for a returnable-bottle review?
Send bottle photos, labelled and unlabelled samples if possible, height, body diameter, neck opening, label material, residue details, expected bottles per hour and the desired final condition.
Can washing remove every adhesive?
No generic claim should be made. Adhesive behaviour depends on the label, bottle, chemistry, mechanical action and process conditions, so sample testing is the safer approach.
When is a new-container rinser a better route?
A rinser may be better when bottles are clean, new and only need loose-particle removal before filling, rather than full washing or label-removal preparation.
Need this checked against real bottles?
Send bottle photos, dimensions, residue details and the required wash result so Lancing can compare the right machine route.
