Thanks for the heads up. I think I'll go with the I2 Tri-Clean suggested. It's not available at the link above but I found it at and ebay.co.uk seller that ships to Sweden (http://www.ebay.co.uk/itm/Gtechniq-I2-Tri-Clean-500ml-Antibacterial-All-Surface-Interior-Cleaner-/252958036011?hash=item3ae579502b) so I figure I'd throw in a couple of more products to save on shipping costs. Couple of Gtechniq MF1 ZeroR Microfiber Buffing Cloths are fine? (It's what Gtechniq suggests using with the cleaner).
Also, while I'm at it, do I need a special cleaner (and mitt) for wheels for lacquer protection or wheel cleaners are mainly to remove brake dust and heavy road dirt that car shampoo's can't?
Gtechniq microfibres will be perfect.
Wheel cleaners are not protectants for lacquer. They are used a a pre-wash spray, to aid removal of brake dust and other dirt and are personal choice really, but if you do use a wheel cleaner, make sure it's non acidic, as the latter can damage lacquer and if there's any slight weakness in the lacquer such as a kerb mark, acidic cleaners get under it and can cause damage. Non acidic wheel cleaners such as ValetPro Bilberry Wheel Cleaner is fine and best used at dilution ratios of 1:8 or 1:10 for regular maintenance use as a pre-wash (to the normal wheel wash), and at these dilutions won't strip any protection you have on the wheels.
However, wheel cleaners are not the same as products such iron removers, and so won't shift embedded brake dust or iron deposits which build up on all wheels (and body work) over time, but a wheel cleaner will prevent build up as will good wheel sealant/wax. Iron removers and tar removers such as Iron X and Tardis are the products that remove embedded iron/brake dust/fallout and tar/glue/sap, that normal washing won't touch and are best used 2/3 times a year. These products will strip any sealant or wax so you need to reapply protection after use of them.
A wheel mitt is a very good choice. Choose a microfibre one and as well as being great for gentle washing of wheels, they protect your hands from the sharp knuckle shredding brake guards. Another product to consider for effective wheel cleaning is a set of Wheel Woolies, which are brilliant for all wheel jobs, and tailpipe cleaning. They are pricy for a set of 3 different sizes but a very good long term investment as they last years if looked after. Most good detailing gear websites sell a version of them.
