The exact number of times the May Grunwald solution can be reused varies depending on factors such as the number of slides stained for each use, temperature, humidity, and exposure to air. Users are expected to evaluate the stain quality for each batch of slides stained and change the solution once the stain quality diminishes. It's important not to return a used working solution back to the stock bottle; instead, used solutions should be stored tightly capped in another bottle, ensuring the cap is always tightly closed to prevent evaporation of methanol and water pickup from the air, which can cause the stain to precipitate out of solution.
