A method of web cleaning, particularly relatively soft polymeric webs, without using dipping baths or ultrasonic energy. The method includes conveying the web against a backup roller and spraying the web with a high pressure liquid while the web is supported by the backup roller. Thereafter, residual fluid from the high pressure stream is stripped from the web by a gas curtain while the web is supported by the backup roller. In many convenient embodiments, the web is contacted with a cleaning roller while the web is in contact with the backup roller.
