Differential Case
Just pulled my differential/batwing for some gear upgrades. The case is stained from grease and road grime. Wire brushing doesn't seed to do much. Is there an aluminum cleaner out there that will help bring back the finish?

Did you try Simple Green? Another option I can think of is to clean it real good and spray it with aluminum finish paint spray. I think Mid America sells spray paint for magnesium finish valve covers for L98. |

Re: Differential Case
Sodium Hydroxide. Closest thing to it that they will sell to the public would be '409'. I buy the base chemical by the drum.

Re: Differential Case
I`ve used muratic acid to clean parts before but i think i`ll try the sodium hydroxide the next time. Work with it every day and never thought about it. We use about 500 gallons every other day in a vessel regeneration process. The vessel is used for boiler feedwater purification. They`ll never miss a couple gallons.

Re: Differential Case
What gears are you going with?
Also, have you tried anything like brake cleaner or engine degreaser? I'd think they aren't damaging to aluminum.

Re: Differential Case
What has worked for me is once you get the crud off buff it with 0000 steel wool. It also works real well on aluminum parts under the hood and front suspension.

I tried engine degreaser, it gets the crude off, but doesn't bring back the case color at all. Jagdpanzer is selling me the gears and installing for me, he may have some ideas on cleaning. Rich

This stuff was so aggressive I don't knoe if I would use it on the differential case. Next time, I plan on using it only on the inside of wheels and do so with the wheels dismounted. |
