Hi Guys
Did a B*gger of a conservatory clean today, years of 'ingrained' dirt build up on white frames and sills.
I knew it was like that so after reading a post on here recently someone was recommending 'Doktor Power' and elbow grease so got some in just in case, sure enough TFR wouldn't touch it so was time to get hands dirty and do some Graft!
Doktor Power sure enough worked a treat.
The trouble was this conservatory had been so neglected over the years that the UPVC no longer shines, even more so after the aggressive Doktor Power paste treatment.
This job was a commercial 'End of Tenancy' clean for a new client so didn't matter that it doesn't shine, so much as its now clean to hand back.
With a job like this, what is best product to restore a shine to UPVC (for future ref) please.
I did read on here that UPVC restorer doesnt work, so do you know of any good way to bring back a shine?

Cheers as always guys
Goochie.
