mms color

i have bought mms and 4% hyd and when i mix the drops it goes a dirty brown color and then a yellowy color. before i have always used citric as activator and it went yellowy amber color, so i am a bit concerned as to whether its ok and havent used it yet. has anyone else had this happen. thanks for any advice

If you have a new bottle of MMS you could try activating it with 50% citric acid and compare the results with 4% HCL. 

thanks but i only have the hcl. and am suspicious of it as i oce had bad mms

thanks i have ordered kit from here to deliver to uk  which i had not realized i could do as so many say they cant deliver.  i dont trust others since i had bad batch
