Been donated haul of brewing equipment with out of date never opened chemicals

[Janulka098]

Been donated some equipment. Two demijohns with 25 l fermenter, old heater, two part air locks and big bag of out of date chemicals. Does anybody know if any of these are useable or shall I just chuck them? None of them were opened.

kwik clear - bbe 16
tronozymol -bbe 16
wine tannin - bbe 16
potassium sorbets - bbe 17
pectolase- bbe 15
tartaric acid - bbe 17

shall I just dump the lot?

I'm no expert but punted the web...
Tartaric acid and potassium sorbate unopened should be stable and OK
Kwik Clear (looked it up) gelatin one part and kieselsol which is colloidal silics (sand?) should also be OK
The rest likely will have degraded

I wouldn't risk using them.

Thank you, I think I will dump the lot - probably not worth it :) thinking about it. Was extra with the gratefully received fermenter and demijohn
thank you a lot for your advice
