Milano has a efficient public transport system, and is very easy to blackride. There are gates at subway stations which can easily be jumped or sneaked following people, be careful cause personnel can stop and fine you, just don't let them see you. Checks on tramways and buses can happen, just pretend as the stupid foreigner who didn't know anything and can't speak italian, most probably they will let you go, if you have a regular document the fine very hardly will get to your real place, if they ask you for cash/card payment just say you have no money.
Accommodation & Wild Camping
Hospitality exchange community is one of the biggest in italy, there are weekly meetings in Colonne di S.Lorenzo.
Parco Nord (tramway 31 or 4, taking from yellow subway zara or maciachini) can be a nice spot to camp. Big enough to hide, lots of tap water. Parco Lambro may also be a good place for free camping. However, there is risk of theft in either park. All other parks inside the city (Giardini di Porta Venezia, Parco Sempione, Parco Solari) are closed during the night.
If you hitch at Monte Stella, there are plenty of long benches in the park and a public water tap nearby. It's a good place to stay on a summer night.
There are several public dormitories where you can find free assistance, though often you can be asked to show you are with no belongings etc.

Shower & swiming

Dumpsterdiving in Milan can work pretty well. Openstreet markets and supermarkets (e.g Lidl in Maciachini metro line 3, soon to be updated on Trashwiki) as any big city in Europe throw away lots of good food that you can easily save, not being very popular nor known the concept you won't find so much concurrence.
Free cantines can be found at Caritas, Opera S.Francesco per i poveri and several others, you can ask in Central station "help desk" for homeless or in Piazzale Lodi (metro line 3), in lots of public libraries they should have also addresses, soon to be written here.
Food for homeless, poor people are called "Pane Quotidiano" (It means "daily bread"). They usually give some bread, pasta, vegetables and sweets every day without asking you money or papers from 7:00 to 11:00. One is located in Viale Monza 335 you can arrive easily there with the Red Metro Line in Villa San Giovanni the other one is located in Viale Toscana 28 you can arrive there with the bus 90. You can recognize it easily because you can see lots of people waiting there

From 2011 Milan has a new very welcoming policy for street performances. There is an official website http://milano.stradaperta.it/start.htm where you can register and book your position/timetable time by time, you just need a valid mail and address (no matter where) plus practically even if you fail the registration and go directly busking with no registration police normally doesn't care and let you play. All the pedestrian walks from the castle to Missori (via Dante, via Mercanti, Piazza Duomo, Corso Vittorio Emanuele) are very good places, on the website you can also see a map of the official busking spots and bookings from other buskers..
