what do you use on upvc,connys and gutter cleans?
I have a 5l canister of TFR with about 4.9L left in it that I'll never use.
Now I just carry a strongish mix of Fairy and pure water, and I only use that once every couple of weeks, perhaps. A really minging conny roof might get some, but that's it. Other than that, it's plain water all the way.
