No more dirty, boring sinks – all you need is a glass!

Rub vigorously to polish dull areas and enjoy the result.
Bicarbonate

Baking soda is a must on this list. Create a slightly abrasive and polishing solution with a glass of product and a little water at a time, poured in a trickle, to obtain a pasty cream.

Apply to compromised surfaces with a soft sponge, rinse and dry. Here we go!
Citric acid

Citric acid is nothing more than fermented citrus juice. Beyond the term that may lead us to think of an industrial chemical, it is totally natural. Dissolve 150 grams in 1 liter of water, take a single glass, dip the usual sponge in it and rub it all over. Then, as always, rinse and dry! However, avoid using them on marble or natural stone surfaces because you could ruin them.
Alcohol vinegar

If you want to do it even faster, use alcohol vinegar. Just one glass is enough to use in the sink that has already been cleaned as best it can. Soak a cloth in it, wring it out and wipe it carefully. No need to rinse and everything will shine again!
