Am I wrong or did some guy on here last yr say that Frank Red Hott dissolves corrosion great on those brass or copper contacts in the harness connectors?

Or was it cola or something?

 

Oh! I remember seeing this on Mythbusters. They put like salsa on jailhouse bars to try and dissolve them and it worked I guess, but they had to electrically charge the salsa and all that.

 

Sprite does pretty good on copper...

 

Anything containing a relatively high pH citric acid works well on copper. I use a mixture of salt and lemon juice to clean the copper bottoms on my cookware at home. Ounce for ounce, you come out about the same using electrical contact cleaners, whether they be in a spray can or a pen. Might as well use the solvent created for that purpose as opposed to trying out home remedies.

 

The 'Real Deal' is a product called Deoxit. Comes in a 100% strength solution called D100L, and a 5% aerosol. I'm using the full strength D100L on my injector connectors now - cleans all the crud off down to bare metal - shiny copper. Do a Google seach on Deoxit, and you'll find lots of places selling it.

 

the corrosion is basic so a acid will get rid of it, i would imagine diluting some vinegar in water will do the same thing as hot sauce

Pop is acidic also so it would work, but wouldnt it be sticky after?

 

i always use WD40 then ad connector grease. seem to work fine

 

Ever thought about what acid might do to the plastic on the injector? The injector plug? Wire Insulation? Anything else you might spill it on while leaning over your engine? The results will vary with what type of acid you use.

I've bought my '90 SE 5 SPeed new - and I've fought the injector connector corrosion problem well over a decade. Tried everything; WD40, ChemTool, vinegar, baking soda soln, various electrical contact cleaner products along with dental picks, emory boards, you name it. Some worked just well enough to give either give intermittent operation of the injector -or- lasted only a few short months before I had to do it again.

Nothing gave a clean lasting metal electrical contact without harming other parts except DeoxIT. I follow that up with Coppershield on both sides of the contacts to prevent further corrosion.

 

I think that may have been me who got the idea for, and tried the hot sauce'd injector connectors.

Sorry to report, that it didn't work too well. I used brake parts cleaner before hand to clean off the old dielectric grease and other contiminants. Then I did the hot sauce treatment. I followed up after the hot sauce with baking soda and water, but all that didn't get the job done. I noticed there was a "crust" that needed to be scraped off mechanically to restore the fresh metal terminals. And I noticed some "green" growth inside some of the really bad ones... like what you might see around battery terminals that are corroded. Bad stuff!

I ended up disconnecting the injector terminals from the plastic connectors (that part is actually quite tough... you can't just force them out! got to release the tab "just right") and then mechanically scraped the surfaces with a precision screwdriver. That is the only thing that has worked for me. And I bent the connectors so they would give a really good "pinch" to the injector terminals.

I was all set to cut the connectors off completely and solder on new connectors I sourced from the dealer, but ended up being satisfied enough with my manually restored, old connectors that I am just running those for now. No misfires yet... engine is running great.

 

put some tapitio on that ishhh jp

 

you dont want food smells,they attract rodents

 

kinda looks like ATF
