Aqueous Cleaning

Aqueous (water based) cleaning methods have been investigated and there are commercially available aqueous cleaners. In the commercial world there are divided opinions about whether it is advisable to use aqueous cleaning for films other than release prints. Concerns involve the high value of camera original and duping materials and the potential hazards of improper drying, such as water marks caused by poor drying or even blocking.

This method is not as thorough in removing greases and oils as solvent systems. There are drawbacks for this method, especially the stability of gelatin in decomposing films. There may also be issues regarding the water absorbed into the base not being fully removed after drying and acting as a reservoir of water for further decomposition.
