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.

just found this on the Tinternet, anybody tried it?

Got dull uPVC window frames? Polish them up with cheap car polish to restore the as new shine. Dirt beads off every time it rains. Have even tried this on the soffits & barge –boards (the plastic bits near the roof) with amazing results but get somebody to foot the ladder first!

Any kind of cutting polish will work like t cut etc, its the same principle to bring a shine to most hard surfaces...

I believe silicone sprayed on a rag will do it, the same stuff they put on car trims like bumpers and plastics for back to black, it's not actually black, it's clear and brings out the colour of whatever it touches and gives a water beading effect

I would wonder whether it would last though.......car polish wears off after time, surely so would this, esp with brush and pure water on it after a month or so.....?

[GDwindowcleaning]

A cutting car polish actually takes off the top layer and cuts down to new bright plastic, its not a wax based polish that sits on top to give an extra gleam...

If you use any kind of cutting polish/paste, it will remove the surface of the pvc which will result in a dull finish.

It wont cos its just more upvc underneath

Oh really?? well use some t-cut as you suggested and then look at the difference between that and some other part of the frame or cill

[GDwindowcleaning]

I have and its come out fine, i used to paint cars for a living and worked in the window industry...

[rg1]

If you worked in the window industry then you will know that any abrasive will scratch the surface and these will attract dirt. You will also know then that there is a coating on the surface of pvc which which gives it a shiny look. Once you remove it, pvc will always look dull whatever you use to try and restore it.

[GDwindowcleaning]

No actually the finish on the upvc is part of the extrusion process as the dyes are precision engineered. There is no coating its just plain old upvc....

If you t cut a car does it leave it dull? T cut is a cutting polish so it does both jobs, if you just used a cutting agent it would leave it dull and then you would need a separate polish to shine it back up....

It may be abrasive but it doesnt leave any visible deep scratches, if you looked at most surfaces including upvc under a microscope you will see loads of imperfections....

[rg1]

T- cutting a car is not the same as t-cutting plastic, but I guess you're the expert on cleaning Upvc so I'm not going to argue with you.

Why do people get the hump so easily, I am no expert but I have done this in the past and its worked. I have also been on factory tours and seen the stuff made so know a little about its composition. I am sorry if you dont like my opinion...

No offence, and I certainly don't have the hump. You just seem reluctant to accept any opinion other than your own.

We will just have to agree to disagree

[GDwindowcleaning]

We certainly can and thats fine with me but it cuts both ways, we have obviously both tried it and got different results so we are bound not to agree lol...

Have a good day chief...

lol.......upon scaning down this topic i was getting double vision

Interesting points of view tho.....and obviously nobody else dared chip in with their experiences!

I use Siroflex UPVc solvent cleaner. It's made for that job and is used by the industry.

It's removes grime, dirt, etc, etc, and also those black scuff marks from shoes.

Loads of places sell it online. Coast about £4 a ltr.

Solvent is the ideal cleaner for obvious reasons. Although you need to be careful when using it as it can melt upvc

Yup. It's not a good idea to splash it on like water. It's best to wet the suface first and then put some on a damp sponge.

After a bit of trial and error, it's easy to work out how much to use to do the job. The results are amazing and instant.

It's also essential to wear protective gloves because it'll turn skin to parchment.
