This 20oz can is the best carb cleaner I’ve ever used, and honestly I’ve used aboutall you can think of, including house brands.Most run out so quickly they surprise you.Even some 14oz cans seem to empty in just a few minutes.Berrymans gives you true 20oz of product.Some carb cleaners seem like regular old brake cleaner, and never seem to do anything other thanmake the carb wet. They even shut a running motor off.Yet others seem like nothing more than relabled ether, and are ok for looking for gasket leaks (increased idle), but evaporate so fast, there is no cleaning action.Berrymans will actually clean your carb, and I don’t mean make it shiny.I mean dissolve crap that builds up from years of sitting and letting gasrot in the bowl.If you have an old 70s smog motor, and you pull the intake and the cross over is full ofbaked in carbon, this will really help clean it out too.For $5 a 20oz can, I strongly recommend getting 2 or 3 cans to have on hand.It’s worth it.And i’m not paid to say that.

B12 chem toll has been around forever. Always uses when the old rides are gummed up. Got these real cheap too. Asked if my mileage improved … I dont know! Car hasnt hit the road yet. The only downside was one of the cans had a nice screwdriver shaped hole in it and was leaking inside the box. The other three cans were good. I will always get the chemtool. Spray or pour.

Got some in my mouth from spray ricochet. Tastes awful! Cleaned the carb up good though.

I have used other brands as well and I think Berryman has strong cleaning power.

I didn’t want to deal with walnut blasting my 2.0T motor for carbon cleaning. This stuff plus manual abrasion did a great job.
