Need help not sure if this is a evap line or positive. Your help and advice would be much…

How long have you left it for ? If it's a result after 5 minutes then it looks very faint positive but you're better off getting red dye tests

It came up within the 5 minutes. Is the red dye tests more effective then blues tests

I think its blue, not grey, so must be positive! :)

@kerrymorris567, the red dye ones are easier to tell

I'd say positive xxx

Well I did a test with red dye and it came back negative xx
