Hi all

Looking forward to Spring ...

... when I come to clean the white-work(?) of our new porch, built last
year, is there anything that can be recommended to clean it well? Or do
I just use car shampoo or something similar?

I use warm water with a little washing up liquid, and a sponge.
Don't use anything abrasive.

Of course I'm aware that various specialist cleaners exist, and indeed
I'm happy to buy one of them, but I'm wondering if they are simply
expensive "snake oil".

There is a PVC cleaner you can get from your local PVC stockist (probably
on a local industrial estate). Might be useful if you have any stubburn
marks after first washing, and it's used by installers to remove any
dirty finger marks, but probably not suitable for the annual wash.
