Cleaning buffing compounds off aluminum


2004

I NEED TO KNOW A GOOD WAY TO CLEAN BUFFING COMPOUND OFF ALUMINUM [BILLET] WE ARE HAVING TROUBLE GETTING OUR PLATING TO HOLD ON THE CORNERS. WE ARE GETTING WHAT I CALL BLISTERS WHERE THE PLATING IS NOT STICKING ON THE CORNERS.

Dear Mike,

Yes...you can not plate without removing buffing compound. You can try a solvent, n-bromo propane, either dip or spray. But use proper goggles [linked by editor to product info at Amazon] / chemical rubber gloves [linked by editor to product info at Amazon] etc. You can also try out with Henkel-Loctite range of products ( please contact local dealers)

Good Luck

This is a rather general answer, Mike, but I think the best approach is probably to add ultrasonic cleaning to the process.

Ted is right, an US cleaner is perfect but... also expensive.

There are quite a lot of chemical cleaners that can do the job even without US. Most of them operate at high temp, like 60-80 C and almost neutral pH. Ask your supplier for a buffing removing compound. I am sure he will come up with an adequate product.

Similar things happened here. After buffing the aluminum, there's residue of compound sticking there, but our company managed to clean with a product called Cosmoline. I believe that's available in many places already, but you can compound that by yourself, utilizing xylene/ pce/ and butyl cellosolve.

Well good luck,
