How much did ya claim for car washes? 
Interesting question - not much consistency year on year:
y/e 30 Apr 2014 = €9 (3.3 months trading)
y/e 30 Apr 2015 = €12
y/e 30 Apr 2016 = €36
y/e 30 Apr 2017 = €6
y/e 30 Apr 2018 = €51
01 May 2018 - 23 Jan 2019 = €30*
Total for 5 years = €144 ... includes all expense on interior cleaning and exterior washing.
*includes two €10 car washes - immediately before door sticker removal and immediately after the same i.e. expense incurred on disposal.
