Ya it is OK but I Use just a little and do it cold....
(sorry to disagree with amandabab).
Use less and a longer soak,,, say over night, with cool water.
Next day HOT RINSE.
Using a low concentration, cool water, and a hot rinse will make sure you do not build up any "SCALE" which would ruin your beer.
Like all chemicals it is a question of Duration or Concentration
