The yellow spray called elbow grease is fantastic at removing stains on white clothes. Spray it on, leave it to soak, stick it in the wash. Even works on white trainers!
Method multi surface spray in tangerine (I think) is the beast kitchen surface cleaner ever. Even takes the splattered oil off the tiles behind the cooker.
Steam mop is a must for laminate floors.
Plants can change the old look of a room. Even if you like the minimalist look a wee floor plant just finishes the room off!

I painted my really boring grey cement slabs in the back garden last year with white paint and a stencil, and it made it look so much better. I know its a but Pinterest naff but we couldn't afford to replace them and I was so bored during lockdown 🤣. It only took me a couple of hours and about 40/50 quid and everyone comments on how good it looks.
Use a fluffy sock to clean venetian blinds.
