"this method is THE BEST BY FAR!!!!! it is EASY & FAST!!! & relatively CHEEP too!!!!


OK... i just figgered this out last weekend...arguably the BEST method i have EVER used to clean Cotton gauze air filter media....i have been cleaning these types of filtersd for about 20 years now & nothing REALLY seemed to CLEAN the stuff thoroughly......


This started because i have an SRT intake w/a AFE filter, & i was cleaning it the usual way: spray on the cleaner let it sit.. .rinse it out... blah blah... it seemed to work OK... but i could ALWAYS still see dirt & crap stuck into the filter media down deep in the grooves/pleats... this was pissing me off... so i cleaned it three times the last time ...
soak with filter cleaner..let sit, .rinse...
soak again w simple green, let sit in the HOT sun...& rinse...
then AGAIN, soak with with orange glow cleaner & simple green then let sit & rinse....

STILL there was dirt & bug parts & oil grime down in the pleats & even at the ends of the outside pleats..... WTF!! & you DO NOT want to blast it from the inside with a water or air hose.. .you will damage the cotton that needs to stay in good shape to filter properly....


Then..I had an idea......


I got a small bucket... dumped two scoops of that Oxy clean crap /powder in it & then placed the filter in there.....next i poured 1 1/2 $1.39 2 liter bottles of generic CLUB SODA in the bucket.....(about 3 litres total...dep on the bucket you use...use a smaller one to use less Club Soda etc...)

WELL!!! that **** bubbled & foamed up almost Instantly & this greasy dirty film & TONS of dirt & crap just freaking JUMPED out of the filter gauze!!!!! the foam was all topped with this yellow filter oil & dirt & grime & bug detritus .. .it was amazing that all this crap was STILL in there after cleaning it traditionally 3 times..... the Club Soda was the trick for SURE the carbonation in that just 'boiled' the crap out of the cotton gauze fibers instantly...!!

SOO much crap came out i ended up using a piece of paper to scoop the nasty oily grime & dirt & such that was riding on top of the foam in the bucket out & dumped it so i would not have to lift the filter up & out thru that ****.... i swirled the filter around in the solution for about 3- 4 minutes & then let it sit for a minute or three.....finally I just shook it in the solution for a few seconds & pulled it out... OMG.. .it was CLEANER than NEW!!! I mean it was SPARLKING clean!!!! elapsed time: 10 minutes MAX!!

ALSO....this is VERY gentle on your filter media.. .(cotton gauze) & is MUCH better than blasting it with water & or air trying to rinse out the crap or blow it out all of which are highly discouraged by the filter makers....

let it dry properly, (Note without all that residual grease & grime still clogging the filter.. .it WILL DRY MUCH FASTER !) then oil it up & reinstall.... i actually have two filters so i do not have to wait on drying & oiling the filter to drive my car when cleaning filters i just keep one all oiled & clean & ready then i can take my time cleaning drying & oiling up the other one....

you can use ANY cleaning degreasing solution I would imagine...it was the Club soda not the 'Oxy clean' that made the HUGE difference.. but feel free to copy this method to a 'T' if you want to...."

Doesn't the OXY bleach the cotton?

[JgY]

Thanks for the post. This info will definitely come in handy for me.

i dont think the OXY bleaches anything. Ive never used oxyclean but from what i remember on the commercials he put scoops of oxyclean in a tub of colored clothes also...i remember seeing a red shirt...cant truely confirm this...

[Doc_Yizz]

I've read thousands of times that the dirt buildup actually helps the filtering process. I've always cleaned my filters gently, and they always look a lil dirty.

[madchef]

interesting read....oxy clean doesnt contain bleach btw

think this would work on a non oil filter?

TNX , ChicagoX....I've transfered a copy to our DIY forum.....

[O HELLA JDM]

this question might be off topic...or on topic...is this better than using a filter cleaner...or like a K&N recharger kit or what ever....just wondering

[chobble19]

can this method be used with injen cold air filters as well?

You need to oil the outside of the filter. Without it, the filter would not be as efficient in trapping dirt and other contaminants.

[Jeff92se]

True. But you have to end up buying a new one every time.

Not really, a long life filter. You still wash them out with their cleaner, but don't oil them.
Problem is the AEM only comes in cone styles.

For factory use the Amsoil nanofiber filter. You clean it with low pressure shop air every 10K or so. That's all. No oil. I think it's good for 50K miles.

Number for the G35 is EAA74.

/me goes off to buy some oxiclean and club soda. my pop-charger is filthy!
