Removing dried WD-40
I know some think of WD-40 as the "go to" for everything, but
After hosing something down, 5-10 years later the volatile solvents have evaporated leaving behind a stiff gunk. So, my question is how do you remove it? For example on a typewriter that some idiot hosed it down with. -- "I am a river to my people." Jeff-1.0 WA6FWi http:foxsmercantile.com |

That typewriter was jamming or rusted and WD freed it up. ...... Phil |

I'd say it came out pretty clean. https://cdn.discordapp.com/attachments/685910956580405312/754506691353116722/unknown.png -- "I am a river to my people." Jeff-1.0 WA6FWi http:foxsmercantile.com |

Removing dried WD-40
a) WD-40 is 100% volatile - over time. Please look at the MSDS if you have any doubts.
b) The sticky -slimy skunge left behind when it is (under) used is the old hardened lubricant that has now been evenly distributed throughout whatever was sprayed. https://files.wd40.com/pdf/sds/mup/w...sds-us-ghs.pdf Peter Wieck Melrose Park, PA |

Yep: http://www.aetherltd.com/images/tty15-2/typebarscleanedmore.jpg http://brassgoggles.co.uk/forum/index.php/topic,43672.0.html It's clean, but now you get to lubricate it from scratch. I used to work on those when I lived in Smog Angeles, but haven't done any rebuilds in the last 50 years. Model 15 lube and adjustment manual: http://www.aetherltd.com/public/model15manuals/138_Model15_Adj_Oct41.pdf The original lube was allegedly whale oil based, so you're not going to find any of that. My guess(tm) that's why the oil turned to tar or varnish. I think if you dig deeper, you'll find more varnish. You may also need to tear down the main shaft. I didn't have much luck with ultrasonic cleaning and had to use acetone to get rid of persistent varnish. I recall using either light clock oil or sewing machine oil which have the advantage of not evaporating and having a stable viscosity over some temperature range. It's been a long time, so check the forums for the latest suggestions. If you need any help from me, forget it. I'm busy untrashing my house after moving the entire office home. Good luck. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

Removing dried WD-40
a} Please read the MSDS for WD40. It is 100% volatile. Really.
b) The nasty, sticky skunge 'left behind' by WD40 is not from the WD40, but what was re-distributed by the WD40 all over everything. c) How to get rid of it: There are various solvents that are quite effective depending on the substrate. Brake Cleaner is one. Carburetor Cleaner is another - again, depending on the substrate. There are many others. Ans there is always the dishwasher. d) First-cause was not enough WD40 in the first place, sufficient to both dissolve and then rinse off the skunge. e) WD40 is neither a lubricant, nor an anti-oxidant, nor a cleaner, nor much of anything else other than a material designed to displace water. And it does that exceedingly well. All the other 'off-label' stuff is much like adding aspirin, chelated iron and Karo syrup to Christmas Tree water. Does it work? Peter Wieck Melrose Park, PA |

Peter Wieck Melrose Park, PA Here's what bothers me about WD40 despite what the MSDS says. I've used it where there was no previous lubricant, and found later than it crusted over. I used it twice, once on an HDMI connector on the back of a bluray and the other on a micro USB connector on a wifi extender, both a bit touchy due to contact issues. Yes, I know it's not a contact preservative but any clean lube works fine off label. Several months later, both quit working. Removing the connectors revealed white crusty material on both the connector and inside the cables. I ended up using WD to flush out the crusties and then flushed out the WD with Free All. No more problems. |
