Piston polish in La Pavoni Pro

by **mitmind** on Wed Aug 17, 2011 4:35 am

Hi
After I fixed the heating element, I was waiting for the new brass piston and the gaskets, thanks to Peter the waiting wasn't too long ;-)

As you can see the old plastic piston after 10 years of heating's status

So the first some good polish

Now hard cleaning on the portafilter gasket seal

Some results

And build everything again to do some real tests ! !

Hope U like It

I hope you clean everything up obsessively since Autsol is not food safe: http://www.deep-reflection.com/sites/de...l-msds.pdf

Ohh yes tekomino

Of course I did, I cleaned pretty hard with a powerful soap and then y preheat water and citric acid and let it do for some like 2 hours.

After I rebuild all I run 2 complete boilers with nothing else than water

And thanks for the advise

I'd like to polish my machine up at some point....is there such a thing is a food safe metal polish?

we have this stuff in the bike shop called 'chromax'
it's labelled as a biodegradable and non-toxic metal polish
and although not listed as food safe,
it smells just like that stuff the dentist uses to polish your teeth after a cleaning..

it doesn't work very well
