Installing 32-bit Wine 1.7.19 on 64-bit Ubuntu 14.04 [duplicate]

I'm having a bad time trying to install 32-bit version of Wine 1.7.19 on a 64-bit version of Ubuntu 14.04. I've got through all the questions related to that on AskUbuntu but I haven't found a working solution probably because I did a big mess with Wine (tried to compile/install it in many ways, winetricks won't work until I use ent WINE="path" winetricks, etc).
I would like to make a cleanup of everything that's related to Wine (and its components like winetricks) and perform a clean install. I tried to install Wine through the Software Center but there's only an old version of Wine, then I uninstalled it with Software Center as well. Then I used this tutorial to compile Wine: http://www.noobslab.com/2014/05/winehq-updated-to-version-1719-install.html - I compiled it in "/home/kamil/Pobrane/wine-1.7.19" but it made a 64-bit version of Wine. So basically I have two questions:

  1. How do I clean all traces of Wine to perform a clean install?
  2. How do I install/compile a 32-bit version of Wine 1.7.19?

First, if you've made a mess, you could start cleaning your wine config:

rm -rf $HOME/.wine

Then add the oficial wine PPA to your sources:

sudo add-apt-repository ppa:ubuntu-wine/ppa -y && sudo apt-get update

Finally, install the 32 bits version.

sudo apt-get install wine1.8:i386
