I was looking for something to clean off some oil spreading around the fill and drain plugs of the differential so I could paint it. Here in California any chemical that works is banned. It's impossible to find a degreaser that works. Looking around the Internet I found a brake and parts cleaner in a spray can made by Wurth. It says on the can, "Not for retail sale", but you can buy it at Pegasus Racing for less than 6 bucks. I sprayed the oil on the diff with this stuff and waited for it to dry. There was no runoff on the ground below where I sprayed, but when it was dry the oil was gone and it was bone dry. What makes this so good in this case is the diff had been sand blasted to a rough surface. I did not think it would be easy to get out. Heck I got to buy more of this stuff. No financial interest, just a very satisfied customer.<div id="yMail_cursorElementTracker_1490598980184"><br></div><div id="yMail_cursorElementTracker_1490598985026"><a id="linkextractor__1490598989315" data-yahoo-extracted-link="true" href="https://www.pegasusautoracing.com/productselection.asp?Product=3393" class="lEnhancr_1490598990828">(HAO) Wurth Brake Cleaner - Pegasus Auto Racing Supplies</a><div id="lEnhancr_1490598990828" class="yahoo-link-enhancr-card yahoo-link-enhancr-cardSize-medium yahoo-link-enhancr-cardType-yenhancr yahoo-link-enhancr-cardCategory- ymail-preserve-class ymail-preserve-style" style="max-width: 400px; font-family: "Helvetica Neue", Helvetica, Arial, sans-serif; position: relative;" contenteditable="false" data-url="https://www.pegasusautoracing.com/productselection.asp?Product=3393" data-type="LINK_ENHANCR_ATTACHMENT_TYPE_INLINE" data-category="" data-embed-url="" data-size="medium">
