I have been using Pink RV antifreeze for years in my horizontal
bandsaw. The pump has been submersed in it for 7 years or so. I
never goes bad and stuff never seems to grow in it, but it does
evaporate slowly. I just add more. I use it full strength. The
Anticorrosives in it seem to keep rust at bay as well. Its a generic
7x10 bandsaw.
I buy the stuff anyway to winterize my boat, so I always have some
around. Last time I bought it for just over $2/gallon.
Distilled water is quite corrosive. I would avoid that by itself. See
the link below:

However I buy gallons of distilled water from the market to dilute full
strength auto antifreeze.

IIRC RV grade antifreeze is propylene glycol and often flavored with a
bit of methyl salicylate. Easy to tell if you have it all flushed out.
You will be able to taste the oil of wintergreen long after the pink
dye is gone.

Greetings all;
I have just found that food grade antifreeze in the water seems to
be a nono for long term useage as motor coolant.
Why do you need food grade in a recirculating system? How
about plain old antifreeze, which has lubes and
anti-corrosion additives. Or, they make a coolant for TIG
torches that has the same stuff.
I've had the same stuff in my TIG torch for over a decade,
and it still runs fine.

I'll get some 50-50, about 5 gallons and change it. After only minimal
useage for a year, this stuff is really ugly pink snot. I need to caulk
around the line cord too as that is the only place insects can get in an
drown. The rv stuff must smell good to them.
The amplifier came back. I'll send a check Monday.
Thanks Jon.
