We used to pick the leading brand of air fresher whenever we do our grocery routine on month-ends. It costs more or less P300 ($8) and sometimes it didn't even last for a month. It actually consumed a big chunk from my budget where I could already buy a lot of supplies with that amount. Whenever I cook something in the kitchen, which is only a few steps from the living room, my children couldn't take the smell especially fried fish as it is so stinky and brings unpleasant smell. We don't have an exhaust fan. Could you imagine our everyday dilemma facing that fishy smell or unpleasant odor. Oh, well not until I visited a friend and witnessed how she made her natural air freshener. I got curious as it smells good and you wouldn't even think it's a home made freshener. When I got home, I tried to make the same freshener with all the ingredients available in the kitchen. I use a stronger vinegar, Heinz apple cider but I'll try the white one next time. I bet you wouldn't buy the one in the market once you tried it. It smells like a morning breeze.
So here's how to make a natural freshener: Vinegar, calamansi and detergent. Mix them together and put in a spray bottle. That's it. You now have a natural air freshener. Spray it in your room or any place you want.
Edited: Use the commercial or white one instead.
