How many of you regularly clean up your AC vents? - especially those of you who drive around mostly in the city- which is an environment of dust and smoke? I have had my ford fiesta for around 3 years now, and have given it that 'once in a while' cleaning a few times.
This time around, I tried to see how much of dirt actually stays in your AC vents without you realising it.

I gave the vents a clean 2 months ago, and how I do it - I'll put up pics.

Do keep i mind that I use the car in Mysore city mostly, and it is one of the 'greener & cleaner' cities. The long trips to Tamilnadu are made once in a month, and those too - to village areas where there are not many vehicles around. Trips to bangalore (one of the most polluted cities!) happen maybe once in two months.

So keeping this picture, I shouldn't be expecting a great amount of dirt right?

The cleaning of the vents:
The ford fiesta vent openings are nicely spaced, and the direction plates are widely spaced which allows easy passage of cleaning devices into the .

The duct gets a good all around wiping - and the result?
see below

The dirt on the sponge- only 1 vent cleaned till now - 3 more to go! The water I used to clean sponge - turned a variety of hues - finally settling for the one below -

After this step- I took out a can of 'Neutralizer' made by 'Gulf' (saw it in a departmental store) it has a long serpentine tube in white.

The can has to be shaken 4-5 times before use, so do it before you clip on the tube to the can. You clip on the tube to the can spray top, and put the other end of the long tube deep into the AC vent - You have to take care to spray ALL around the vent tube - you'll hear a 'swoosh' sound as Foam begins to come out of the tube and fill the AC vent. Spray till the foam reaches the vent opening.

Once you have sprayed ALL the vents, close the flaps, and leave it for 15-20 minutes
DO NOT TURN on your AC as you'll be spraying the car with foam, and your kids'll think Christmas arrived early.
