For organic dirt use acetone first, next use water or detergent. For other than
organic dirt use diluted acid solutions (soluble salts of hydrochloric or nitric
acid) or base solutions (ammonium or sodium base).
To remove ACIDS use protophilic solvent (sodium carbonate), to remove
BASE use protogenic solvent (mineral acid of various concentration).
In case of heavy contamination use brush and detergent, nevertheless avoid
detergents containing large and hard molecules which could potentially
scratch glass panes.
At the end of the cleaning process rinse the pane using distilled water.
Use soft brush with wooden or plastic handle exclusively to avoid risk of
scratches. Do not use wire brush.
Rinsing is a necessary cleaning process stage allowing to remove remaining
soap, detergents and other cleansers from the panes prior to their
reinstallation.
After the preliminary cleaning process stage, rinse the pane using running
water first, distilled next.
Avoid drying the panes either using paper towel or forced air circulation since
some fibres, grains or contamination of other type could permeate into the
panes thus causing weighing errors.
We do not recommend using driers when drying measuring glass tools.
It is a frequent treatment to leave glass components on a rack to dry.
Cleaning powder-coated components:
For preliminary cleaning process stage you need running water or wet sponge
featuring large pores, this will help you to remove loose, heavy dirt.
Do not use cleansers containing abrasive substances.
Next, using cloth and cleanser-water solution (soap, dishwashing liquid)
gently rub the cleaned surface.
