Hi, thanks for the replies.
By proper stuff - supermarket bleach is so weak you will not get the best results - it’s ok for a maintenance clean

I’ve got a 10l can of hypo from a mate, that’s all sorted.
I was trying not to buy anything that needs more costs in postage, so was hoping that the supermarket bleach would just be the surfactant.
By weak, did you mean the hypo content, or weak as in the ability to do the job?
Thanks 👍
