Also, Amin cleaned the stove & kitchen floor to get rid of the oil scum. He used this spray product called 'Easy Off' Oven Cleaner. The spray is so strong that you don't have to scrub the surface. Just wipe it with a cloth, piece of cake.

Well, this was when things went wrong. Amin also used the spray on the filter above the stove. Guess what happened...

Conclusion: One problem solved, another problem comes up hahaha
Another thing we did, we changed the air filter for both Ford Focus & Subaru. My car smelled quite bad since winter. It smelled like damp clothes that you don't dry it up properly. Well, I thought maybe because the car is always in the garage, so maybe it got the smell from the cooking etc. Then I tried a few things: parked my car outside, turned on the A/C often. Still, it didn't work. Amin said, maybe the air filter is not working anymore..

So Amin did some research about changing air filter. We found out that it is recommended to change the car's air filter every 6 months / 1 year. This service is not included in regular maintenance schedule. So if you just go to a dealer and ask them to change it for you, they will charge you a lot, maybe around $100+! What most people do (and what we did): just go to Walmart and buy an air filter for house (allergen free, only cost you $25), cut it out (we got 6 pieces) & install it in the car. And I have 5 more, for another 5 years! :D
