Q: How do you clean a refractometer after use?

A: Important! After every measurement, use a lint-free, absorbent cloth to remove the fluids from the prism surface

[2] and prism cover [1]. Then carefully clean the prism and prism cover using a cloth moistened with water or if

necessary alcohol, and dry both parts using a soft, dry and lint-free cloth.Normally, it is sufficient to use a soft,

preferably lint-free and absorbent cellulose cloth to clean the measuring prism. First take up the sample with a cloth,

then wipe with a moistened cloth. In most cases, water is a suitable solvent.
