I just took over an entier round from a guy who used LOADS of fairy in his water.we use wfp and have had no problems and no complaints, just use a little more water than normal and it should be fine.
swapping over to wfp for most of my round and its prob too late for me to start using gg4, so should i be worried or just give an extra scrub, rinse and put up the flow rate?
Would agree with Jeff1 - clean all the frames up while your still on the ladder makes job much easier - we find explaining to customers that the first couple of times may not be perfect, offer to go back and re-clean if un-happy and say the advantage of the system is frames will be clean (as long as thats what you intend to do)Good luck
