Comma CAC500M 500ml Carb Clean Aerosol

Great product. Cleaned out two of my small Honda engine carburettors really nicely. Comes wit useful applicator straw, to reach more tricky areas, and give a more direct/accurate spray. The product does its job, and gets rid of dirt and much really easily, as well as some rust. Would recommend, definitely.

Decent flow rate blows gunk out of carb passages and cleans the oily gunk off the outside. Straw cap works well. One can did just over one carb from filthy to sparkling. Took two to do all three on my bike.I have used a few different cans over the years and this stuff works as well as or better than the others.

Used this to de gum my lawn mower jets. worked well in conjuction with some compressed air, cheaper than replacing the carb.

Used this to clean my Ford Focus throttle body. Wasn't expecting much as isopropanol (IPA) had struggled. Wow! You don't need to use much at all, let it soak for a bit and use an old toothbrush and rag if you have to.What I would suggest is, remove the throttle body first if you can as this stuff is very strong (and for safety). Don't use it on the MAF which really should only be cleaned with propriety cleaner or IPA as this is too strong, wear neoprene gloves and DO THIS OUTSIDE as it's toxic and flammable.If you do clean the throttle body and/or disconnect the battery you may have to go through the process of getting the engine-management unit to 're-learn' the throttle settings. This step is recommended by many manufacturers and is vehicle-dependant. Easy enough to find video help online which you need to check as there can be important safety issues with working on a 'live' t-body.Oh and by the way, the car idles better and the automatic gearbox appears to 'shift' at a more sensible rev-point.Loads more left in can for dreaded EGR clean . . . .

It's very good at shifting light varnishing on carb bowls but I found it useless at unblocking blocked jets - even after leaving to soak all night. Ended up having to boil the junk out of them.As a word of warning don't wear cheap disposable gloves while using this as it will dissolve them instantly, and then the lady in your life won't let you anywhere near her for a week until the smell has gone from your fingers

A must have if you have a petrol lawn mower or a motorcycle

Used it to clean my Air flow meter (Maf) under advisement from a Land Rover guru as its less than half the price of 'Air flow meter cleaner' and does exactly the same job. Also used it to clean my throttle position sensor. Top product and price.

My car was running very rough. A few squirts of this through the jets and chokes of the Dellortos seems to have cured it for now - and a few squirts on the outside of the carbs. has improved their appearance too.
