During the pandemic, microphones should only be used with a wind or pop shield, which is to be replaced with every new speaker. Under these circumstances you should dispose of the wind shield after use.
The re-use of pop or wind shields is only recommended to a limited extent. If the re-use, however, is absolutely necessary, foam wind shields can be cleaned in warm water using, for example, washing-up liquid or mild soapy water. It is important that the pop or wind shields are only used again when they are completely dry (it takes approximately three days to dry). Of course, the official hygienic rules and recommendations must be followed during the cleaning process.
