Ultrasonic cleaning black floats
« on: April 13, 2024, 11:00:14 AM »
I got an Amazon special ultrasonic cleaner which has been great for my carbs. I know fluid has been controversial, with all kinds of opinions on vinegar, Simple Green, and various other fluids potentially damaging aluminum. I'm using Simple Green Extreme, which is safe for aluminum:

I have a question about cleaning the black floats with it. Will it damage the float material? I've cleaned them all except the floats because I wasn't sure. My plan is to put them in a large tea strainer that I bought to contain the small parts and give them a quick blast if it's okay to do so. It's a nice day here, hoping I can get them cleaned and installed today...

According to the link for simplegreen in your post it is safe for plastic so go ahead! I have used chem-dip on my floats in an ultrasonic (20 minutes) and had no issues with it. Went ahead and rinsed them with water immediately after just to be safe.

Would that be the floats on the carbs that are now pissing fuel? ::)

Nope, different floats! I have new floats on my Pearly Girly and she's still blowing some gas out the intake. Gonna try a later spark and see if that helps.

But yeah, back to the original post. Ultrasonic away! If you are still paranoid just put a single float in the cleaner and see if it starts to disintigrate. That way if it does, you only need to buy one float and not a whole set  ;D

Thanks all! One final ultrasonic cleaner session with the carbs... then back together and see if I can get them on the bike in time to enjoy this gorgeous Sunday weather!

I don't see why a float would need an ultrasonic bath ever.

Because you haven't dealt with carbs from a USA bike that sat with MTBE in them for years.....
