RELAX
The Reduction of Electroencephalographic Artifacts (RELAX) is an open source extension for EEGLAB that provides a fully automated method to clean EEG data.
Downloading RELAX:
To download and install RELAX, click on the source code in the "Assets" section below, and unzip into your EEGLAB plugins folder.

New cleaning technique:
Additionally, we have recently published a pre-print providing a method to target wICA cleaning to specific artifact periods and frequencies. Details about this new cleaning technique can be found in the following pre-print, which should be cited if the targeted wICA method is used:
Bailey N.W., Hill A.T., Godfrey K., Perera M.P.N., Rogasch N.C., Fitzgibbon B.M., & Fitzgerald P.B. (2024). EEG is better when cleaning effectively targets artifacts. BioRxiv. https://doi.org/10.1101/2024.06.06.597688
RELAX 2.0.0 also makes available MWF cleaning with the ability to set sparse delay embeddings in the MWF cleaning approach, which our pre-print suggests enables better cleaning performance than just using consecutive samples as the delay embeddings.
Instructions can be found in the Wiki (the fifth button from the left in the toolbar at the top of the webpage).
