I had sent my chrome grill parts over to my sandblaster and he tried to clean them up, but as soon as he started the parts started to warp. He isn't set up for baking soda, so what else can I do to remove chrome?
Nothing that I know of if you want a smooth clean ,unplated surface. Baking soda will not do it. Your best bet is having a chrome plater reverse the process, basically a chemical -electrical strip.
yeah I don't have a plater close by that's why I'm looking for different options. I am painting my grill anyway so I expect to do a little smoothing and body work.
Don't bother to take the chrome off, simply use PPG's DPLF40 and spray it...it sticks like glue...then paint if whatever color you want. R-
A big BS to that. It will not stick to the smooth finish of chrome well enough to stay put. A nick or two and the stuff would come off in sheets at a carwash with the pressure wand when he was trying to get bugs off. Read this, from PPG: DPLF Epoxy Primer mixed 2:1 with DP401LF or DP402LF Catalyst provides an excellent corrosionresistant primer. This primer provides excellent adhesion to many types of properly prepared metal, fiberglass and aluminum substrates, as well as plastic fillers. DPLF Epoxy Primer may also be used as a sealer and topcoated withmost PPG Refinish products. Smooth and unprepared chrome plated surfaces are not considered "properly prepared metal surfaces when it comes to painting.
Small parts , toss in a bucket with warm water and hardwood wood ashes mixed together. Basically a strong lye, be very careful not to get on your hands or splashed on face or eyes. Rinse parts with water after, scrub with brush and liquid dish detergent. I have used this successfully on small chrome and painted pieces. Do not use an aluminum bucket or aluminum tools to put lye mixture in. Give it overnight to work.
Weeee-eeeell, I guess the bumpers on my Studebaker didn't know they weren't "properly prepared" then...I ran them painted for almost 10 years using DPLF40 and lacquer paint...Yep, they chipped but never had an issue with a car wash wand...maybe you guys in Canada have higher water pressure than we do in the states...!!! At any rate, what's "all 6's and 7's" got to lose, other than a bit of primer and paint...it's definitely not like it's going to hurt his chrome...!!! I think the REAL wording here to understand is: "are not considered properly prepared metal surfaces." Doesn't say anywhere it definitely does not work and won't stick...!!! R-
Box ém up and freight them to a plater. It costs peanuts to do a reverse chrome. I got an old flaking chromed beam axle and two split bones done for $20NZ ($15US)
I would also vote on sending them to a plater. It's an inexpensive process to de-chrome stuff. And a lot less work too.
I have done a light scuffing on chrome but it was in good shape with no defects. Held up good for the few years I could keep an eye on it.
Glad to see trying here since facebook did not turn up to much, that link was all i could find. good luck
Like said before it is cheaper to remove at the platers than re-chrome . I had an axle that chrome was shot. Total for removal was $30 dollars.
My plater had the grill and bars sandblasted to firstly remove the scale and areas where it was delaminating. He then dipped everything and reversed the process to leave nice metal to work with. Took a little longer but well worth it. He was able to fill all the small pits and do a proper triple plate job.
Ive wet sandblasted body parts without warpage. Basically its the use of a commercial pressure washer with a wand that pulls the media into a mixing head on the nozzle. No dust, no heat.
