Actually they are correct - Whink Rust Stain Remover has HF acid only.  Their   
   other rust and iron stain, rust and oxy etc have a host of chemicals- this one   
   is only HF.     
      
   Here is the safety data sheet link - for those who don't know this virtually   
   all products have to produce a safety data sheet available to the public upon   
   request.  I had requested this one because I was getting ready to order and I   
   always do this with    
   new products.
