Do not store the used cloth in a closed container – some solvents remain in the cloth and must be able to ventilate.
Use of this cloth with the Universele stained glass putty is highly recommended. Works faster than the traditional gray stained glass putty. For the water soluble putty: if the cloth is lightly moistened with water then putty residue can be quickly and completely removed. For the traditional putty: always use dry.
For studios that place stained glass into double glazing: use the cloth after the sides have been sealed to remove any residual putty.
You can also use this cloth for computer monitors: all the dust will stay in the cloth!
