I've been using a piece of purchased software for years which cleans my PC after use. In addition to the main wash the software also has custom washes, one of which is ZA Extreme. I have recently renewed the licence and now the ZA Extreme marker is 'greyed out'. I have spoken with tech support for the software and they do not know why this has happened, nor were they much inclined to help!! The software enables me to create my own custom wash but I'm not sure what I should be washing for ZA Extreme. When it was working the custom wash removed megabytes of stuff from ZA.

So, my question is what should be washed, and where will I find it?
