I'm a bit annoyed. In -laws borrowed our carpet cleaner, plus loaned them two large, full bottles of detergent - one of carpet cleaning solution and one of pet-stain remover spray.


They returned everything today (my husband received the items) and took us out for lunch to thank us. But when we got home I realized they had used almost the entire bottle of each detergent. This is bizarre to me because their apartment isn't much bigger than ours and we only used about 1/2 cup of solution for a thorough cleaning (we hadn't even used any of these bottles which were both new).


It costs about $50 to replace both bottles. My husband doesn't want to ask them for money because they paid for our lunch.


Well - lesson learned. Anyone who borrows our machine in the future can buy their own detergent.
