Just recently we've bought a TDG01 calibration grating. We would like to use it in non-conventional way. We are intending to use the groves and ridges of calibration grating as a support for fibrillated material. Such application will require frequent cleaning of the surface of calibration grating. We would like to ask are there any recommended ways of cleaning the grating ? Is it safe to clean in ultrasound bath ? There are also methods which involves covering the grating with glue-like products. After hardening such layer of glue is peeled of from the surface of grating with all the contaminations (https://www.afmworkshop.com/newsletter/271-methods-for-cleaning-afm-reference-calibration-samples). Since the grating is formed on the chalcogenide glass coated by Al, we would like to know if this is a safe procedure?

Polysaccharides can be purified with ultrasonic water. It is possible with the addition of non-ionic surfactant. Aluminum interacts with alkaline and acidic environments. Therefore, the aquatic environment must be neutral. Can be cleaned with ethyl alcohol. Ultrasound will help further.
Yuri Mirgorod Unfornunatelly, ultrasonication, HIUS and even ethyl alcohol treatment was not succesful.

Hence the scallops are not coated with a polysaccharide. If with glue, then it was necessary to write with what kind of glue. Your source is not readily available to consultants.
