We never use HF acids anymore. Look up the stories and you will most likely make the same conclusion. I don't think too many municipalities will allow it as well- even if you contain the run off.

If a wheel is that bad, we use our steamer.

Years ago my employee used HF acid on some wheels- Porsche. The more they stained, the more he sprayed!!!

I had to hand polish all four wheels. They came out fine so I was happy not to buy him a new set and he was really pleased. So it can be done, but in light of what we know about the stuff, just stay away from it. Some users do it correctly with the right arm length gloves, masks, and attire, but too many have no idea what it's doing, but will someday!

Personally knowing three large chemical manfacturers, and neither will make HF, tells me something. These are companies that have their own chemists and make the stuff- not private label like 90% of what you see. If their chemists advise against its use, it's a pretty easy decision for me. One less thing on my shelves and one less thing for my young children to get into by accident.

If you use HF acid, you should have it locked at all times!! You are opening up a bigger problem than stained wheels if you have it exposed and accessible to others.
