The Reduction of Electroencephalographic Artifacts (RELAX) is an open source extension for EEGLAB that provides a fully automated method to clean EEG data.
To download RELAX, visit the RELAX release page: https://github.com/NeilwBailey/RELAX/releases, and unzip the file into your EEGLAB plugins folder. Alternatively, install RELAX directly using EEGLAB's plugin manager (within EEGLAB click on "File" > "Manage EEGLAB extensions" > search for RELAX).
Further information can be found in the publication manuscripts, which must be cited when RELAX is used:

Additionally, we have recently published a pre-print providing a method to target wICA cleaning to specific artifact periods and frequencies. If the targeted wICA method is used, the following pre-print should be cited:
