Thompsons UPVC Restorer 480ml

My PVC windows are over 15 years and the sills were grey, I had sharpie, wood stain, fence paint and gloss paint marks to remove as well as the usual scuff marks and this product managed them all.I'd tried various cream cleaners, magic erasers and acetone cleaners in an effort to turn my sills back to white, but to no avail.This product is a bit of work to use, but it isn't difficult, or require force. It's best to do on a fine day, and only do small sections at a time.It's suggested to put it on with a damp cloth, I found that if the cloth was too dry, then the product didn't work anywhere near as well. Properly wet, but not dripping worked best for me, but I was doing this on a baking hot day.An old toothbrush is brilliant for getting into all the tight spots and window seams, and was particularly useful for the tougher marks and stains.You wipe most for the debris and dirt away before you start, apply the product ( similar to a slightly thicker cream cleaner) with a wet cloth, wait for it to dry slightly, then 'buff' it off with another cloth, pretty similar to polishing a car.I found if you do about 2-3 foot sized window frame at a time, that was about right, if you wait until the product dries 100%, it is harder to buff off, just wait for it to be touch dry, then buffing is so easy.A few strokes of the initial product was enough to turn my grey sills to white before my eyes. Harder marks, such as wood staining / sharpie etc took more strokes and a little more product. I found that using more force didn't make any difference, just more passes made the difference, the old toothbrush here made a world of difference, my hardest stain ( sharpie) did take about 2 minutes of toothbrush brushing, but perseverence paid off. It didn't look like it was going to come off completely at first, it started black and then faded, but eventually it suddenly went from a medium grey line to completely gone very quickly, and there was no sign of it on my bright white door. For the wood stain and fence stain, the same was true, but they came off a bit faster.Any product spilt on the glass came of easily after drying with just a wipe with a dry cloth as the product dries to a powder. I did find that if the product dried too much to a point it was harder to buff, it came off as more of a powder and created some mess. Any wet product spilt on paving was harder to remove.In all I would highly recommend this product, it's not a quick 1 wipe and it's done job, but it did a fantastic job and was really easy to use. In addition it removed a variety of stains and marks that I didn't think I'd ever get rid of totally, it seem to be long lasting too, I certainly don't think I'll need to repeat the process again for at least a year, probably more.

I cleaned all of our UPVC with this this - windows, doors and conservatory (a good workout!). The product doesn't perform miracles - i.e. it doesn't remove scratches (but it does fade them) and nor does it remove all marks and stains. It does however leave UPVC looking restored and cleaner and it does remove marks that water and soap can't. You can think of it like car wax and rubbing compound in one, and it leaves a shiny and smooth finish on treated surfaces. Just be sure to follow the instructions on the bottle and use a soft damp cloth when applying (this will make your life a lot easier). It was certainly worth the time and effort it took to treat all of our UPVC with this, it all looks much better for it.

Great product, a little bit goes a long way! Impressed on the hard stains it got out the door, saved me a the cost of replacing it! Will do another application once I’ve finished decorating!

Works but results are inconsistent. If you windows have been cleaned for an extended period (likes our when we moved in) then probably best look elsewhere.

Used product cleans pvc well

Has significantly improved look of the black laminated door our house had when we bought 11 years ago. It had faded due to sunlight (why previous owner chose black on a south facing door is a mystery). Applied twice

Move into a new house with 14 UPVC windows all of which were grubby and looked liked they hadn't been cleaned in years. Had already used a few different cleaning products, all of which had made a difference, so i thought i had got them as clean as was going to be possible. However thought i would try this stuff given its good reviews. Very simple product to use, wipe on /wipe off, or wipe on then leave to dry then wipe off (bit easier method). Surprisingly this stuff made a big difference, managing to lift out really ingrained discolouring and getting the UPVC back to being a bright clean white colour. Overall a good product.

I don’t usually do reviews but this stuff is fantastic. It’s brought my 25 year old window frames up like new.
