I had a major problem with this at first, but now I use two sets of
plates, so one pair can be left to soak in a very mild alconox solution
overnight... The original (5-6 years old) plates are still going strong..
When washed with ddH20, I find that I get very clean gels,
particularly if the water can be applied as a 'jet' (or poured from a
reasonable height) onto the bottom inch of the plates... seems pressure
rather than quantity/quality/heat works best for me.
I don't know about Sigma plates, but I've had problems with their
spacers and combs not fitting very well - hope it's not the same with the
plates. I WOULD recommend using double the number of sets you have at the
moment, as it reduces junk build-up on the surfaces.
