Remove Leading and Trailing Zero's

Experts,

I have a WHERE condition that strips out characters (" ", "-", "0")
I have encountered an issue with stripping out the "0".

How could the below WHERE condition be modified to to strip out only the LEADING and TRAILING ZERO's?

This is a continuation of a previously answered question here:

thank you

UPDATE [import-CSM2] INNER JOIN tblLetterOfCredit ON [import-CSM2].[Guarantee Code] = tblLetterOfCredit.GuaranteeCode SET tblLetterOfCredit.GuaranteeCode = [import-CSM2].[Guarantee Code]

WHERE (((Replace(Replace(Replace(Replace([LCNO],"-",""),"0",""),"/","")," ",""))=Replace(Replace(Replace(Replace([Reference Number],"-",""),"0",""),"/","")," ","")));
