Comparative tests have revealed that tissue handkerchiefs used for nose cleaning contained considerably less bacteria than conventional textile handkerchiefs.

The results applied also to pathogenic bacteria including Pseudomonas aeruginosa and Klebsiella pneumoniae.

Tissue handkerchiefs are – in terms of hygiene and freedom from infection – significantly better than textile handkerchiefs.
Altogether the results, under hygienic evaluation, advocate clearly the use of tissue handkerchiefs for nose cleaning.

The research was carried out in 1994 by a team from the University of Erlangen.
