    Hi guys!

    Winter is coming, it's raining and snowing in the Balkans, and my wipers are smearing badly due to Gtechniq G1 rain repellent.

    I tried everything to remove this crap from my windscreen, including all purpose cleaners, IPA, Megs's Ultimate Compound, etc. And failed.

    Do you have any ideas on how to remove this crap without damaging the glass?

    worst windscreen moment I had as a lorry leaked hydraulic fluid on my screen, I pulled into a layby and it came straight off with some petrol on a rag might be worth a try it should not harm screen but wash afterwards in case. let us know if you try and results

    That's proper old school mate... But it will work but in the 21st century even normal glass cleaner will do it , or high alkaline class wash with a sponge.

    Gtechniq G1 and G5 are not crap products, in fact they are one of the best rain repellents out there tried and tested. I have been using G5 for 2 years now with no smearing or juddering whatsoever. I think something else on your windscreen may be causing you problems or your wipers are knackered although you shouldn't be using them that much anyway. :Smile:

    Thanks guys.

    I tried literally everything, and it won't come off. Tried the vinegar method as well, and it's still there. Perhaps petrol will do the thing.

    My wipers are several months old, almost new. I clean the blades on a regular basis with APC and a microfibre cloth. So it's not the wipers.

    I can't believe this thing is so strong...

    Some guys on the web recommend Halfords Intensive Class Cutter. Where can I get this product (apart from Halfords website - they don't ship outside of UK)?

    "Halfords Intensive Class Cutter" - perhaps traditional T-Cut would work as an alternative to that? Have you thought about emailing G-Techniq themselves and asking for a solution?

    I emailed Gtechniq last week, no response yet.

    What is T-cut? Any links?

    It's just a cutting compound, primarily used to remove the top layers paint that are oxidised or UV damaged. It may work to remove the GTechniq G1 if you think the Halford's version would work. Example from Amazon UK.

    If you have a clay bar try that with a suitable lubricant. As suggested may not be the G technic if its contaminates the clay will remove may also remove the G Technic if its that.

    Coca Cola, WD-40, Brasso (the fibrous kind, not the liquid), or even Rain-X might shift it

    I see. I tried Meg's Ultimate Compound #105 by hand and failed. Perhaps a machine polisher will do the trick.

    I doubt it. A strong abrasive compound failed to remove it, so I don't think a clay bar will manage.

    I managed to remove it with Meg's Ultimate Compound M105 followed by Meg's Finishing Polish M205 on a DA.

    Pretty strong stuff...
