New dishwashers often come with stickers inside the door advertising detergent and rinse aid for marketing purposes. These stickers are usually placed there by the manufacturer or retailer to inform the user about the recommended products for optimal dishwasher performance. They might also include specific brands or product lines that the manufacturer endorses or has partnerships with.
Whether or not these stickers should be removed before use depends on the user's preference and the manufacturer's instructions. Generally, it is safe to remove the stickers as they serve no functional purpose in the dishwasher's operation. Some people prefer to remove them for aesthetic reasons or to keep the dishwasher's interior clean and free from any residue left by the stickers.
However, before removing any stickers, it's a good idea to consult the dishwasher's user manual. The manual will provide important information about the dishwasher's proper usage, care, and maintenance, including any recommendations or warnings related to stickers or adhesives inside the appliance.
If the manual does not mention anything about the stickers, you can proceed to remove them carefully to avoid leaving any sticky residue behind. You can use warm soapy water or a gentle adhesive remover to clean any leftover residue without damaging the dishwasher's interior.
In summary, the stickers inside dishwashers are primarily for marketing purposes and can be removed if desired. Just make sure to check the user manual for any specific instructions or precautions regarding stickers before removing them.
