I bulk buy soda bic, white vinegar and Castille soap...They do everything!
A bit of soda bic scrubbed around the sink brings it up super shiny, it is a great exfoliant.
White vinegar in the kettle, boil, leave over night or as long as you can, top out and rinse in the morning. You can even save the vinegar to use again. Gets rid of all limescale.
Soda bic and vinegar to clean drainpipes.
Always have a charity shop bag on the go.
Wipe round bathroom while kids are in the bath, if you have kids.
Have a place for everything. We come in, shoes off and in box in porch before we go in. Coats off and hung. We have a couple of baskets in the porch with seasonal stuff in, so at the moment it has ice scrapers, hats, gloves etc. In summer sun hats, our foutala towels which double as sarongs etc (we are on the beach most days) sun tan lotion etc.
Bag rack indoors which holds my two bags (quite minimalist here), one large leather shopper and one small cross body bag. On the top are all my reusable produce bags and cotton shopping bags so I don't forget.
If you are supermarket shoppers get a weekly delivery, on a Thursday used to suit us so we were stocked for the weekend.
Put all loyalty cards in Stocard app so you don't have to carry them around.
Windows on trickle vent always. Shut after lunch mid winter before everything cools down, or leave all day in summer.
Bag of scraps in the freezer for stock.
