Ironically, his cleaning may have been rubbish
because you redid them.
Not an insult to your window cleaning but he was trying to take chemicals/detergent off thge windows to keep the water pure and you were probably putting detergent back on them. He turns up the next time expecting the glass to be free of such stuff and cleans with the expectation that no chemicals have been used on the glass since his previous visit.
no he did them b4 we even moved in,it was a contract for these apartments,and i only re did them after 2nd month of livin they,coz my missus step dad uses wfp and she told me that,but the spots were still they after everytime time,prob wernt purifyin his water rite,that my guess
