If you recently renovated your bathroom, sooner or later you will realize how difficult it is to scrape out the lime scale that deposits on the caulking, and prevent mold from appearing.
There exist, of course chemicals to deal with the problem, but we know they are unhealthy and not really effective in the long run. In the video below, though, you can see a super idea. All you will need is large white candle to launch into action against mold.
The method is efficient when used immediately after new tiles have been installed. Thoroughly rub the candle on the caulking between the tiles. Use a white candle, as it will form a transparent layer and will become practically invisible.
The wax coating will form a water-repellent layer in the space between the tiles, thus effectively preventing the appearance of mold.
