RNazol/lung RNA degradation

I use RNazol (4M GITC/sodium acetate) for extracting brain RNA and it
works fine. However, liver and lung preparations end up with a degraded
smear on formaldehyde gel. I vaguely remember someone posting that one
could increase the GITC to 5M and liver RNA is OK. Could someone confirm
or instruct otherwise, best wishes
