    You can try this way using SUBSTRING to replace first and last character of column in table.

    In this example, I have used double quotes(") instead of comma(,). It will replace only first and last character(“), if the column value starts with double quotes(“) and ended with double quotes(“).

    DECLARE @tblProducts TABLE (ProductName VARCHAR(100))
    
    INSERT INTO @tblProducts VALUES ('"Recovery 10x12" Pump Exchange"')
    INSERT INTO @tblProducts VALUES ('"Recovery Pump Exchange 10x12""')
    INSERT INTO @tblProducts VALUES ('Recovery Pump Exchange 10x12"')
    
    --REPLACE Last Char(")
    UPDATE @tblProducts SET ProductName = SUBSTRING(ProductName, 1, len(ProductName) - 1) FROM @tblProducts WHERE ProductName LIKE '"%' AND ProductName LIKE '%"'
    
    --REPLACE First Char(")
    UPDATE @tblProducts SET ProductName = SUBSTRING(ProductName, 2, len(ProductName) - 1) FROM @tblProducts WHERE ProductName LIKE '"%'
    
    SELECT * FROM @tblProducts
    

    Result:
