2004 Ford RTV Tray Back & 2004 Subaru Outback 2.5l
Just recently purchased a lovely set of the WH Statesman alloy rims and the inside of the rims is just disgustingly filthy so could anyone suggest a great rim cleaner that I could use without having to spend hours scrubbing them.
Acid. But I'd only really bother with trade wheel acid. The off the shelf acid cleaners are very weak.
You might have some luck with a de-ironizing product like iron-x or decon gel if they're not TOO bad. Will probably take a few applications and a bit of patience though. Still may need a regular wheel cleaner afterwards as well. Bowden's wheely clean is another product in that bracket.
Armour all have a pretty strong wheel cleaner.
Wolf gangs decon gel is good but will still require a little scrubbing.
Just dont use steel wool or the green scotch brite type sponges as they will scratch the funk out of the rims.
I got a bottle of that armour all wheel cleaner for christmas last year. I wouldnt have ever bought it myself but it does work. Maybe even a bit too strong for regular use (on painted wheels ). I wet the wheel, spray it on then scrub it with a soft wet brush. If i remember right it contains alkaline salts and burns fingers!!
what tinny said. even a strong acid will generally need atleast 2 goes on a filthy rim. off the shelf cleaners will get the job done eventually but will take a long time. you may find that there is some dark spots after it is clean that wont come off, this will be baked in metallic particals that will need one of the de-ironizer cleaners that tinny mentioned to dissolve the particals to get a properly cleaned rim.
only thing to watch is i think the machined face of those rims are not cleared and may get a white streaking look to it with strong cleaners. easiest way to tell if it got clear or not is to grab some metal polish and try to polish it, if the polish doesnt change colour its cleared, and if it goes black then its bare alloy
