I agree - and I'd happily fill a thread about valeting!
If the sort of thing I'm talking about doesn't get the wheels clean, then they are pitted and adding caustic is only going to make this worse and worse.
Pitting or indeed delamination of the lacquer are a nightmare on alloys, the only thing to do is get them refurbished.
One way to avoid damage is to never let the pads run low on the brakes - when the metal backing hits the disc you get extremely small extremely hot filings thrown off which eat through the lacquer (melt it) on contact. These then rust - which is why some alloys look rusty.
These holes in the lacquer then allow water in and after a few winters expanding and contracting you get an air gap creeping across the wheel under the lacquer and possibly the paint too.
Refurb time.
Coincidentally around this time in a wheels life, the inside (between the beads under the tyre) can turn porous - you'll know because they tyre pressures drop to abouot 20psi and you get sidewall damage.
A tyre fitter can apply sealer but its a stopgap. They need refurbed.
Refurbs should ideally start with a complete shotblasting and then either acid etch primer and paint of choice all over or if you are so inclined a powder coating. I don't like powder coating as I can't repair it - I can slap paint on.
One of my mates uses spray stone chip on his wheels. They end up matt black and are easy to touch up. They clean easily, don't really need much cleaning actually.
but my advice is if you think you need strong acid or caustic cleaners, you actually don't - you need new wheels or a refurb. Strong cleaners will only make it worse faster. _________________ Cheers

I got some cheap wheel cleaner from B & Q. Goes under the name of 'No Nonsense' metal claener & restorer.
It is corrosive: it contains the same stuff that's in wonder wheels. Phosphoric acid. WEAR GLOVES, Please. |

Ever got wonder wheels or similar product in your eyes, mouth or a cut on the skin?
It is nasty nasty stuff.
Why would you want to paint corrosive stuff like that on your wheels which cost £hundreds to replace?
Answer: Lazyness. It's easier to slap some runny fluid on your wheels and hose them down and hey presto, they look clean again.
For a few years and then they'll be completely shot to pieces.
Take a few moments and use less potent stuff. You'll find it is easier in the long run.
Look at it this way: I put very good quality wax on my alloys. It makes them easier to clean and protects them from the elements. Many brands make wax specifically for wheels.
Use something corrosive just once and all that good work and wax are gone, washed away leaving your wheels exposed to the elements.
So take some time, polish and wax them twice a year and in between times you'll hardly have to try to clean them, and certainly you'll not have to use anything nasty.
Think of the environment if that helps - washing acids and caustics all over your driveway is bad for your tarmac and bad for the environment. And your wheels. And your tyres. And the valves and wheel weight adhesives.
Come to think of it why would anyone in their right minds use potent stuff?
Oh yeah, I already answered that. _________________ Cheers

I think this thread is in danger of boring the c*** out of everyone. Read the posts and make your own mind up, I think all the information has been discussed . . . unless someone knows better? |

Mind you, if carefully written information about how best (form one perspective) to clean alloy wheels is boring to you, perhaps you shouldn't read threads titled "Alloy wheel cleaner"....?
Might save you getting bored.

I'm currently getting round polishing these wheels, un lacquered mag alloys. Total PITA as they are quite heavily corroded. I have the wheel polishing kit from frosts with mops that fit in a drill but its still a git to get to some areas. Using Mothers mag alloy polish and then a sealer and a layer of wax. They look good when they are shiny though. Thank god the troop has laqcuered wheels, a quick squirt of wheel cleaner, some soapy water and they're clean.

Don't envy that job, but nice pickup.
My old 7-series had those cross spoke bbs alloys, and they were major pita to clean until I came up with my system. Lacquered ok, just fiddly.
Unlacquered....crikey. _________________ Cheers
