DECLARE @String VARCHAR(MAX)
DECLARE @Noise TABLE(Noise VARCHAR(100),ReplaceChars VARCHAR(10))
SET @String = 'hello! DNF.!'

INSERT INTO @Noise(Noise,ReplaceChars)
SELECT '!',SPACE(1) UNION ALL SELECT '@',SPACE(1) UNION ALL
SELECT '#',SPACE(1) UNION ALL SELECT '$',SPACE(1) UNION ALL
SELECT '%',SPACE(1) UNION ALL SELECT '^',SPACE(1) UNION ALL
SELECT '&',SPACE(1) UNION ALL SELECT '*',SPACE(1) UNION ALL

SELECT '{',SPACE(1) UNION ALL SELECT '}',SPACE(1) UNION ALL
SELECT '<',SPACE(1) UNION ALL SELECT '>',SPACE(1) UNION ALL
SELECT ':',SPACE(1)

SELECT @String = REPLACE(@String, Noise, ReplaceChars) FROM @Noise
SELECT @String Data
