Thank you in advance for reading this and helping me.
My husband and I rent the home we live in and currently our one and only bathroom is out of service while the landlord is redoing the plumbing due to serious back-up problems. Our neighbor whom we are friendly with but not very close to has the same landlord that we do and has known about the plumbing problems we have had and sympathized with us about it for quite some time. While we are friendly with this neighbor, we are not particularly close. We do have a key to his home for emergency purposes and for when plumbers or other contractors have needed access to his house while he is at work or out of town. (Some of the plumbing problems affect his home as well and I work from home.)
Currently, my neighbor is out of town. I called to let him know about the plumbing work being done and he has graciously allowed my husband and I access to his home while the construction is going on so that we can use his bathroom which is not being affected by the construction. He apologized about the shower not being scrubbed clean to which I responded that we did not care and were simply grateful to be able to use his bathroom and thanked him. While his bathroom is not filthy (we have been using it as-is), it is very obvious that it needs a good cleaning. There is a lot of buildup from hard water in the shower and his huge 8 foot mirror above the sink area has water marks all over it. My husband thinks that we ought to clean his bathroom after we are finished using it for the week and before he comes home from vacation. I agree that it's proper to clean something that you've borrowed and used before you "return" it. Especially since our neighbor has been so gracious as to allow us in his home daily while he's away. But I guess I'm worried that he will be embarrassed about us cleaning it or feel badly that it wasn't up to our standards of use or something. Am I over-thinking this? Would you do a deep clean of his bathroom or leave it more or less how you found it? Thank you for your advice.
