Ahh cleaming my favourite conversation! (I know, I know I am a saddo!)
I use the Tesco or Wilkinson's own brand bathroom cleaners- both 59p for a spray bottle, and as I clean (well swish & swipe!) bathrooms every day they dont need any real power behind them, so I dont know that they are really good or anything, but they are so darn cheap that I can keep one in each bathroom
Microfibre cloths are absolutely the only thing to clean with! I love mine, and have about 10 so I can wash them as soon as they get even a teeny bit grubby. Value are just as good as premium, so dont pay more than 50p a cloth- unless you want colours of course Which I do, but have so far resisted
For glass I use Mr Muscle if on offer or Wilko's own and newspaper
Fabric conditioner I just use Daisy- Tesco's own. Dont know if it is good but smells nice.
If you want a really good cheap all purpose cleaner then get an empty spray bottle and fill 1/4 with stardrops (about 50p per bottle) and top up with warm water. You can use it for anything then and it is instantly ready. I use it to wipe down all my kitchen surfaces and gloss over the cooker 2 or 3 times a day. Its a fab degreaser.
For my loos I use 10p Tesco's shower gel in the loo brush holder ala Flylady. Smells nice, works well, leaves bubbles in loo and is VERY cheap!!
Cant think of anything else, but if I do I will be back!
