Colin Lindsay Posted December 13, 2021 Author Report Share Posted December 13, 2021 Tried that on my GT6, wayyyy back. Didn't have any effect. I reckon I wasn't throwing the soda bread hard enough... 3 Link to comment Share on other sites More sharing options...
PeteH Posted December 13, 2021 Report Share Posted December 13, 2021 Just an Update the Barkeepers Friend had little effect on the alloy trim/kick plate. Neither did the Brick cleaner. Pete Link to comment Share on other sites More sharing options...
trigolf Posted December 13, 2021 Report Share Posted December 13, 2021 I have a new old stock Mk 1 Grille on my Mk 2. I think you'll find that it was anodised originally like the bumpers. You can get the anodised finish electrically stripped and then polish any pitting out then re-anodise. Not cheap mind - as a one off job.

Colin Lindsay Posted December 13, 2021 Author Report Share Posted December 13, 2021 Today I've tried petrol, vinegar, Autosol, Brasso, Astonish kitchen cleaner, Cif Bathroom Foam and paint stripper. Nothing has even made a dent on that greasy film covering the aluminium, let alone the metal itself. I've no idea what that stuff is, the boot floor and the door shuts are all covered in it and petrol takes it off the paintwork, but not the metal. Tomorrow's another day and i'll try another selection of products. Link to comment Share on other sites More sharing options...

Keep the mix off your skin. Honest, it will attack asphalt/tarmac. 2 Link to comment Share on other sites More sharing options...
Iain T Posted December 13, 2021 Report Share Posted December 13, 2021 How about scotchbrite pads or wire wool (oven cleaner pads?) then a buff up for the show side. Link to comment Share on other sites More sharing options...

Pete Lewis Posted December 15, 2021 Report Share Posted December 15, 2021 this is a wheel silver rattle can resprayed grill Pete Link to comment Share on other sites More sharing options...
Colin Lindsay Posted December 15, 2021 Author Report Share Posted December 15, 2021 Nice! It might come to that. The grille is covered in a kind of hard black glaze that nothing will shift so far, plus a greasy almost yellow covering that sort of comes off with petrol - sort of, but far too much effort required. You can see the black in between the horizontal slats in my second photo. Nothing will shift it! I'm going to try the suggested soap powder paste (thanks Clive) and see how that goes.

Bfg Posted December 16, 2021 Report Share Posted December 16, 2021 You've tried foam bathroom cleaner but I wonder if the foaming upholstery cleaner might be more effective. I've first used it on seats and steering wheels that were about to be scrapped ..I think a prior owner was a mechanic and brought his work home on his hands and overalls, anyway those seats came out looking like new. The foam of course getting into the grain / all of the corners. Otherwise are there no alloy cleaners for wheels ..which get embedded in brake dust and sometimes splattered with grease and tar. ?

You don't want that in contact with ally, especially if hot. But it might shift greasy/oily stuff. It should.... Link to comment Share on other sites More sharing options...
Colin Lindsay Posted December 16, 2021 Author Report Share Posted December 16, 2021 Won't get near it today... one of those days... so maybe tomorrow. I'm wary, as Clive says, of dissolving dirt, grease and the actual grille itself. It's a spare I bought online to replace the dented original so have no idea of the history, and while I'm not looking for concours a shine in the relevant places would be nice. I have a large drum of Hypochlorite concrete cleaner, and might try the merest, the smallest drop in an unseen corner... timing it so that it cleans the metal without dissolving it will be critical.

Iain T Posted December 16, 2021 Report Share Posted December 16, 2021 My wife uses Ovenpride cleaner, you put the grilles etc in a bag and pour in the liquid. Absolutely superb stuff but not for an ali grille. As I said try Brillo pads. Iain Just looked at instructions, you can't use it on aluminium.

Colin Lindsay Posted December 17, 2021 Author Report Share Posted December 17, 2021 Well, the washing powder didn't even make a dent, no pun intended. Nor did alloy wheel cleaner. Will try more suggestions tomorrow. Link to comment Share on other sites More sharing options...

Patrick Taylor Posted December 17, 2021 Report Share Posted December 17, 2021 Phosphoric Acid, mentioned by @PeteH is an ingredient in Coca Cola. The classic trick is to put a penny on and it comes out shiny: not sure what will happen with ally. Link to comment Share on other sites More sharing options...

Wasn't common in Derbyshire! Dandilion & burdock was the thing back in the 60s It lost interest for me when they stopped putting real coke in it. My wife did bring back a couple of coke bags (looked like tea bags) that you put in the corner of your mouth from Columbia a good few years ago. The miners there used them against the cold and conditions. Link to comment Share on other sites More sharing options...

Will try more suggestions tomorrow. I think you have tried just about everything? Brick acid will clean off the corrosion (or should!) but not react too fast with the bare ali. The anodised stuff will be pretty resistant. But I think it is either hand it, plus te contents of your wallet, to a pro, or give it a soak in celly thinners to degrease, then a quick rub up with light abrasive, etch prime and topcoat.

Roger Posted December 18, 2021 Report Share Posted December 18, 2021 It would be interesting to know how ice blasting would work in a case like this. I think it might work but very expensive equipment. Any professionals offereing this service in the area? Has anyone here tried it? https://www.kaercher.com/int/professional/dry-ice-cleaning/dry-ice-cleaner-ib-10-8-l2p.html Link to comment Share on other sites More sharing options...
