[Eeglablist] Is it problematic to run ICA on an EEG recording, reconstitute the data without noise IC's, and rerun ICA on that cleaner reconstituted data?

I am working with data that is very messy such that, for a given file, the
decomposition will contain a noise artifact IC that accounts for >70% of
the variance. Out of curiosity, I reconstituted the data without that high
variance noise IC (the reconstituted data still looked very messy), then
reran the reconstituted data through ICA and achieved a much more
reasonable decomposition and fairly clean reconstituted data. Any thoughts
as to whether this is an allowable method for cleaning data?
