Hi Darren, i dont have any pictures of upvc mind you i did try to get some but it is very difficult to capture results on white surfaces, anyway i got plenty of other good photos on different surfaces which have been very beneficial for us when we are explaining to clients why they should avoid using high alkaline based chemicals, again i am genuine with the thanks as i should of thought of collecting such photos in the past. As they say better late than never. and no i have not shared them with anyone on the forum yet, as there are other resources outside of CIU. Regards Tadgh
The test that I'm continuing to do is on the mahogany grained colour UPVC.
I know you said white would be difficult to capture the results, thought this would be better.
I realise there are other resources than CIU but as this is the only place I speak to you, could I see some if your damage pics please?
Email is in my profile.
Or, even better, could you post some if them on here.
We could all save ourselves some grief if we saw the damage that TFR can do.
