Having a weird issue with our smoothflow products (Guinness & Bombardier).
We do a line clean once a week using the Chemisphere Purple Line cleaner, however after the clean we get a kind of Metallic taste in both, like a slight bitterness.
Also there is a slight vinegar taste from the bombardier?
Any help would be great, we generally do the following
flush through with water
30L cleaning tank across 7 taps
10 minutes contact, pull through 2 pints (line length) repeat x2 until all cleaning fluid spent.
Flush through with about 6 litres of water per tap?
Cider and Lager tastes Ok.
Thanks in advance!
