I have 2 con roofs to do tomorrow and have no virosol until Thursday, they are both very green just wondering what is a good substitute for virosol that I can purchase from b&q or supermarkets

Any caravan shops near you - fennicks caravan cleaner is good.

TFR from car shops

Or use a lemon flavoured washing up liquid, but this could end up a bit soapy

Cheers for the offer Darran but I'm in Ipswich little bit too far for me, just need something more then elbow grease

Just mix a strong solution of traditional cleaning fluid. It's what I use on the finials and the come up gleaming each time.

Aldi were selling some caravan, or similar ( can't remember which ) cleaner the other day.

[Mike #1]

Halfords selling a caravan cleaner it will be the same as TFR or similar .

[chris turner]

Cif cream, squirt on your brush and scrub away. The green will melt off..

What about bleach with some cillit bang it's not glass it's the plastic roofs

I tried the Fenwicks caravan cleaner (available in Halfords) a few years ago but it seemed to take the shine off of the upvc which I didn't like.
I mainly just use pure water, did a minger yesterday afternoon that came up well.
If I use a detergent I usually just use Flash all purpose cleaner and might mix it with Ecover washing up liquid to thicken the mixture up a bit if squirting it on the brush.

Good idea 
Rosskesava told me he uses ecover now rather than virosol with similar result.  As I've also run out and can't be bothered to pay postage on ordering more, I may try that.
