Bicarbonate of soda? that is amazing at removing grease

One of my pet hates there.
Clip on wheel weights used on alloys.

They break the paint and let the rot in. Then its back to the tyre fitter to find out why the tyre keeps going down (its leaking through the rim corrosion the flippin wheel weight started

)

Brian was close, it was a 70% Water to 30% Brick Cleaner. I used a brush that came with one of those dustpan and brush sets from the pound shop.
I have a stone front doorstep that was showing years of filth, I'd also managed to spill paint onto it from a spray can, this was genuine autobody paint. I started to clean the step today with the brick cleaner, and a small wire brush to agitate the filth out of the stone step. I noticed that it was removing everything but the paint, even some grinding specks that had Browned into rust marks. I had to scratch the paint off with a blade before the mixture did a cleaning job.
I put it onto the wheels of the 75 with the pound shop brush and it did the job, it even brought the sparkle back to the paint, it really did the job and I did another cars wheels just to make sure.
Well done Brian....

Basically the same formula as cheap wheel cleaner sprays. Dilute hydrochloric acid. Though the commercial cleaners also contain surfactants to wet the surface better and inhibitors to minimise alloy erosion. You can get them from Home Bargains for a pound a bottle. Acid cleaners do work very well on alloy wheels though if the paint's scratched down to metal, the uninhibited solution will dissolve that as well.
