Went to one of my custys house today only to get "it aint been 4 weeks already" i say its actually been just over 5 weeks!
he then says "well they aint even dirty" you are welcome to go to 8 weeks i say, he agrees, i think his wife would of been happy to stay on 4 weeks, im just wondering how many more custys are going to be saying this

I have to say the windows were still mint and they are on most of my other houses after 4 weeks even the 8 week ones are still very good!!
Surely its about keeping the windows clean so they dont get dirty!!
