I take it the reason the rubber/plastic bulb/hose on my anti-freeze

Might help if the manufacturers suggested rinsing with fresh water

I just this minute checked mine which has been on a shelf in my back

rubbish sack Â* Both the bulb and hose are perished.


I have an antifreeze tester which is over 30 yrs old. Maybe they were
made of better material then but i do wash it out after use.
