- Brug en blød, fnugfri klud lidt dampskylles med vand eller en mild rengøringsopløsning til at tørre overfladen af.
- Avoid using harsh chemicals, abrasives, or solvents, as these can damage the mouse's finish.
- Sørg for, at der ikke kommer væske ind i musens indre komponenter.
6.2 Pleje af batterier
Sådan forlænger du levetiden på det indbyggede genopladelige batteri:
- Undgå at aflade batteriet helt ofte.
- Opbevar musen et køligt og tørt sted, når den ikke er i brug i længere perioder.
