Hi guys Im posting this as a cautionary tale for any noobs. Today I was cleaning in a narrow street of terraced houses, I have been cleaning in this road for about a year now with no problems. Parking is limited which usually means cars are under or very close to windows and because of this its impossible to get ladders up to first floor but with care I have been cleaning with a WFP. During the cleaning on one first floor window today I unfortunately sprayed some pure water over a neighbors car. The guy came straight out and started on at me, I immediately apologized turn off the hose and tried to reassure him that it was pure water & would cause no harm as it was cleaner than even rain water. He seemed to accept that and disappeared inside, only to re appear 2 mins later while I was packing up and started throwing a barrage of abuse at me, swearing and saying he was going to throw dirt over the windows I had just cleaned, he was clearly pissed off with my custy as he said so in no uncertain terms so I suspect I was getting the brunt of his frustrations. I continued to apologise and stayed calm, while he revved on at me, I can assure you a few years ago there would have been blood on the street! eventually I left. I have just sent a message to my customer explaining what had happened so at least he has the heads ups, I'm awaiting his response but fully expecting to lose that job. Lesson I have learned, no cleaning windows that have cars under or near them because although most people are fine with a few drops of water it only takes one who isnt. So in future no matter how much a custy says its okay I will be leaving windows that have cars under or near them.
