Astonish cookware/oven cleaner on a wet cloth brings up white uPVC windows, doors, conservatories etc., a treat, just rinse off the residue.
Works on sticky irons and dull car headlights too.
Dettol mould and mildew remover gets rid of most black stubborn marks on silicone sealant and grout.
I leave my jewellery overnight in a glass of gin or vodka, makes diamonds gleam.
I use an E cloth with just water to clean windows, separate one for TV/computer, mirrors, stainless steel. Marigold do a cloth too which has rubber impregnated in the cloth, my new fave, squeaky clean, literally.
Bought a fluffy glove from Asda for polishing, great for that but has been repurposed for applying my fake tan, wish I’d got two now. Fluffy socks work just as well for both.
I use damp fine grit sandpaper to shine up brass door knockers/letterbox or one of those metal pan pall scourers.
Rubbing a ball of silver paper on chrome shines and de rusts.
White nail polish hides scratches on white goods.
I rub a candle on the runners of sticky draws, butter on squeaky hinges.
There will be a huge surge on the national grid with everyone boiling their weeds!
