Hello All,
I have recently purchased a 2018 Mazzer Mini Electric A and after a thorough clean, a new anti-static screen and gasket as well as fitting a set of lightly used 0033M Super Jolly burrs it is running fantastically. However, it has had a hard life at a well known UK coffee chain and the exterior is a bit shabby. My idea is to remove the scratches and scuffs and give it a good polish but not having done this before I wanted to double check that I was on the right path rather than making it worse!
I was thinking of using the following products from this UK store that would fit to my DeWalt drill. I would be grateful if any members could advise if these would be suitable for the Mazzer or suggest an alternative?
Thank you in advance.
Edward

You should be able to make that kit work to some degree. If you have trouble you'll find the hard way that metal polishing is a bit of a dark art. Aluminum is easier than stainless at least.

Last time I stripped a painted mazzer grinder (and a sailboat mast) I think I found enough pitting that polishing was not going to work. So maybe be prepared mentally to go to the powder coaters and have an awesome color for about $100.

Wear a mask and good luck.

Thank you for the advice! There is not too much pitting so fingers crossed the kit will work. I had thought about painting or powder-coating but at this stage I'm looking to keep costs down.

You can powder coat the Mazzer's and it will turn out. You will need to remove the motor windings out of the housing first though. I've had a lot of luck bringing cast aluminum parts to a local metal polishing shop. Here is an older shot of a K30 I had buffed, it has about the same quality casting.

Vim cream at the dollar store and a sponge or microfibre cloth. Don't use anything abrasive or you'll scratch it more.

In my experience vim has gotten watered down a lot in the last few years. It's still worth a try. I don't know of an equivalent cream based cleaner though. I'm sure there has to be one.

Maybe Wrights?

Thank you very much. I'll have a look at that.
