It's OK to add baking soda or other alkali to a STRIPPED wash, but
NEVER put it in the primary ferment and then distill. If you do, and
your still contains ANY copper, you will severely corrode the
copper, and get blue, ammonia-smelling distillate. Not fun!

More info on the correct way to use bicarb at the above link.
As for fixing the problem: Clean out the still, column & packing, &
condenser with a steaming run of water with household white vinegar
added. 4:1 ratio is fine i.e. 4 litres water & 1 litre vinegar
(amounts aren't critical). Then rinse everything with clean water.
Backflush is fine or dismantle if you can.
Re-assemble the still and redistil the blue distillate. Charge the
still with 2:1 ratio, i.e. 2 volumes water, 1 volume blue
distillate. Make sure you do heads & tails cuts. Try for neutral
spirit ( >95% ).

The bicarb binds with the ammonia in your wash to create a harsh base
that gives you the nifty blue-ness.
To use bicarb to bind with fusels and help neutralize your spirit, you
add it to your second run...*AFTER* having run a stripping run of your
wash once. Run one, stripping, is going all out pot-still style (no
packing or reflux) to get a coarse separation of ethanol and flavors.
Then, add bicarb to the low wines (the product of your stripping run)
and run a few days later...this time, if you're using a reflux still,
carefully modulating your reflux.
You can fix your neon blue spirit by diluting with purified water and
add some lemon juice or citric acid until your pH is 6 or below and
Then, chalk this one up as a first-hand learning experience.
1. Stripping run
2. Add bicarb
3. Polishing run
...in that order.
Hope this helps,
