We generally treat our gel boxes and combs with 0.1 N NaOH overnight and
then wash them to neutrality with DI water (Most of the times this is DEPC
treated water but as pointed out by another resopnder, if your water
system is in good shape this is probably not necessary.)

As far as plastic goes, it is safe to assume that virgin plastic is free
of RNases

I presume that your fomaldehyde and formamide are deionized.  If not, you
might try doing that.

Hope that helps
