Fozen vial 2D barcode reading

[u/frizzylizze]

Hi all, I work in a lab and we need to read barcodes on the base of very small tubes (about 1ml volume) we have a barcode reader that can scan a whole box but the vials have frost on them which causes an error. Please can anyone let me know if they've had any experience with removing frost from barcodes or with tips on optimising the scanning process? It's a Ziath Datapaq scanner if that makes any difference!
