Over the past year or so I've been re-evaluating which cleaning products I really need.
I've found it's much easier for my husband and guests to clean up after themselves if they open the cupboard under the sink and find a handful of items, rather than being overwhelmed by single-use products (stainless steel wipes, anyone?).
I have glass cleaner, dishwasher powder (cheaper and easier than tablets), dish soap, a spray bottle of diluted dish soap for surfaces, and a timber and leather polish. Those plus a roll of paper towel and a basket of clean cloths means it's pretty simple to navigate.
(I also keep toilet cleaner next to both toilets, and laundry powder, pre-wash spray, and bathroom cleaner in the laundry.)
As I've finished single-use products, such as wool wash or floor cleaner, that I've been given, I haven't bothered to replace them.
