ILs: pristine. MIL is so houseproud that it distresses us to spot cobwebs in corners. We wish she had a cleaner. She does too, but FIL insists they don't need one, he can help. MIL doesn't want his 'help'.
My parents: has always been cluttered but clean. They are very old and frail, and now have a wonderful cleaner. But you can see when dm has done the dishes, because they are not properly clean any more. And I'm not sure they notice that the house is getting decrepit. Distresses us, but not, I think, them.
