That first chart I posted in the post above is not that good, you want one with a range like this one instead of just recommended and not recommended: www.hoseflex.com.au/files/EJ%20Catalogue%203.47%20-%20CHEMICAL%20CHART%20-%20S%20TO%20T.pdf

Aloha Bill,
The hoseflex link doesn't seem to be working. Can you check if it is correct please. I have been using the initial one you posted and am curious about the difference.
Thanks Brother!

Final pics. Bronze was not an issue, slight oxidation so we used a little F-13. Church members quite pleased.
Awesome job! Surrounding pavers done as well? I keep saying I'm new and a sponge... lol how long for the project and how much chemical, approximately. I'm just trying to wrap my head around all of the great info I find on this board.

Jesse, this job was about six hours. We cleaned entirely with 3% CH, less than 50 gallons.
We've been contracted to clean the brick mausoleums at one of our local churches.
We contacted the brass/bronze manufacturer and they say the larger flat surface is cast bronze, and the nameplates are aluminum.
I had thought about taping up the bronze surface, but would appreciate any other thoughts or first hand experiences.
if you tape I would try that green frog painters tape. I have no idea how SH reacts with bronze.
I would recommend One Restore from Eaco Chem.

Hi Bob,
I have done a handful of Mausoleum they are easy. DO NOT USE F9! F9 is excellent but not for that.
Jason, did you do anything to protect the bronze? Or is it even necessary?
Bob ,
The bronze was fine I just rinsed pretty fast. But it came out good.
Soft wash the whole thing
Cool pictures/project for your portfolio! Nice work
Thanks guys. Jason, a picture is worth 1000 words. Thank you.
The manufacturer sent me some flat pieces I can run tests on. They also said my cleaning solution should have no adverse effect on their bronze.
I'll post pictures after we're done. Thanks again.
Thank you very much
Thanks Bob
AWESOME on the samples !
Guys do yourself a favor and download a chemical compatibility chart
No roof cleaner should be without one:

Some will show a broad range of metals and plastics. This info will help in your repairs and build materials.
