Pour half a cup of Apple Cider Vinegar (苹果醋) into your clogged drainage, leave it to rest for an hour, the oily grease & hairy stuff which clog inside the drainage will dissolve, no more smelly water outflow in kitchen or toilet.
One night a tiny screw dropped inside my basin drain pipe, causing a loud ‘resonance’ noise echoing inside the pipe for hours. I guessed the screw was stuck by the clogged hairy stuff inside the water drainage. My son tried pouring down a cup of Apple Cider Vinegar, the noise disappeared after an hour because the clogged stuff had been dissolved, the screw was no longer stuck and washed down the drainage.
A bottle of Apple Cider Vinegar is less than $10, a plumber house-call service would cost $100 to $200. (That’s why in some countries a plumber earns more than an engineer. My Singapore regular plumber is a young man driving a sport car and wearing a gold watch 🙂
This Apple Cider Vinegar also can “de-rust” (除锈) your rusty tools, coins. Immerse the rusty objects in a small glass bottle containing half glass full of Apple cider vinegar, close the bottle cap, let it rests for 1 or 2 days until the rusts dissolved, then rinse in clean water.
It has been used by Greeks since 400BC for cleansing, healing and energizing our body.
Ideal for adding flavor in salads.
