These are the best metal cleaners on the planet! Some of our customers prefer Peek. and some prefer Autosol. Now you don't have to decide! We have put together a 100gm tube of each for you try out yourself.
We use these both ourselves and this is what we advise. For heavy corrosion or marking, start off with Autosol. When you have got a reasonable shine, finish it off with Peek, it has finer particles and will give you a perfect shine with no swirl marks.
