I normally stick to my regular cleaner I have used for years, but decided to branch out and try something new. I am so glad that I did! This cleaner works amazingly and cleans VERY well. I have actually used this around my garage for other cleaning other than my carbs!

Great parts cleaner

Well I've never used this brand of carb spray before but I've obviously used other products. Because of the cold I wasn't able to try it on a carb but I was able to use it to clean a few parts I had sitting around my bench and it definitely did a good job with that, right on par with all the other brands I've used before.


Blasts the Crud away

I used this Carb Cleaner on my snow blower for preventative end of season cleaning it did a great job and made my carb look brand new inside. I have also used it on a lot of things i am not suppose to, it just works so fast why would i use anything else.


WD-40 never disappoints

WD-40 Specialist Carb/Throttle Body and Parts Cleaner lives up to a WD-40 product. Powerful cleaning with minimal effort. Spray and let the parts sit and the deposits wipe right off with very little pressure or effort.


Works like a charm

I got this about a month ago and tried it out on my 2016 Chevrolet Silverado 1500. It cleaned out the throttle body with no problem and effortlessly. I have used other brands of carburetor cleaner and this works way better.


Works wonders

Say good-bye to oil residue and any other stubborn build up with this cleaner. Sprays on fluidly with little to no blow back allowing for a nice, clean application. It quickly does the job is intended for My carburetor is the cleanest it's ever been and the performance after cleaning is spectacular.

I highly recommend

WD-40 cleaner does what it should

Used this in place of my brake cleaner the other day and it worked fantastic. It evaporates as I would expect for a quality solvent and while I haven't done any engine work with it I anticipate it will be great for the job. You can expect this to help clean up ay grime and dirt as the other cleaners I've used.
