Sometimes the cloth gets so dirty you can see it. Or it even re-greases your lenses! All the dirt, dust and fat rubs off on the cloth. This is exactly what the cloth is made for. After a while it is so dirty it will not clean your glasses properly anymore. What to do about it?
- Without water
Simply shake out the dust and dirt.
- Wash by hand
Use cold water. Add a few drops of mild soap that is bleach free and which does not contain fabric softener. Let the cloth soak in the soap for a few minutes and then rinse it clean in cold water.
- Wash in a washing machine
Use bleach free detergent, and it should be free from fabric softener. Let the cloth air dry when finished.
