How to remove all special characters except commas?

Per the question, how would I do this in regards to the script below?  Thanks in advance.
declare @string varchar(2000) 
declare @newstring varchar(2000)
declare @num int
declare @code int
select @string = '!@#,$%^,&*(,)'
select @newstring = ''
select @num = 1
while @num < len(@string)+1
	set @code = Ascii(SubString(@String, @Num, 1))
	--- ascii: 48-57 (numbers 0-9)
	--- ascii: 65-90 (uppercase letters A-Z)
	--- ascii: 97-122 (lowercase letters a-z)
	If (@code between 48 and 57) or (@code between 65 and 90) or (@code between 97 and 122)
		set @newstring = @newstring + Substring(@string, @num, 1)
	set @num = @num + 1
select @newstring
