fla 9 Posted March 1, 2012 In preparing for the OBD2 conversion i want to clean up all the connectors really throughly. Is there any quicker way than wd40 and a toothbrush, which will be fairly time consuming considering the number of connectors! Quote Share this post Link to post Share on other sites
Stonejag 10 Posted March 1, 2012 Ultrasonic bath full of meths or IPA (no, not India pale ale) would do it - a mate who used to make jewellery had one. It did a cracking job on PCBs, they looked factory-fresh! Between £30 and £80 on eBay should get you a decent one. Quote Share this post Link to post Share on other sites

Stonejag 10 Posted March 4, 2012 That's because both Coke and Pepsi are dilute solutions of phosphoric acid. Use proper acid instead (citric works well, you can buy it in bulk online) and you won't get nasty sugar deposits on everything! Caustic soda works wonders on aluminium but you can't leave it in too long or it dissolves... Quote Share this post Link to post Share on other sites

Ultrasonic seems the best option as you dont need to agitate, brush or anything. In th emeantime, is there any adverse effect for leaving connectors for some minutes in Turps substitute or meths and then cleaning witha brush?

Stonejag 10 Posted March 4, 2012 Every time I mention it people get confused, I always mean isopropanol :) Cleans and degreases so well I never use anything else, and dries with no residue. Pepsi is definitely phosphoric acid, even says so on the label :) Quote Share this post Link to post Share on other sites
elliott 10 Posted March 4, 2012 Small dremel tool with wire brush attachment? Did the trick on my abs ecu connections. Quote Share this post Link to post Share on other sites
