==Penetrating and lubricating oils== [[File:Pb blastergallon.jpg|thumb|left|444px|PB Blaster penetrant, also available in aerosol cans]] [[File:W-d 40.jpg]]<br style="clear:both"/> Penetrating oil is a low-viscosity oil that can penetrate into the area between threads on fasteners. A stuck fastener is sometimes repeatedly heated, sprayed with penetrating oil, and then tapped with a hammer. If heating or hammering is not possible the penetration can be improved by first spraying brake cleaner on the stuck fastener and following with the penetrating spray before the brake cleaner has evaporated. The solvent penetrates better than oil and will pull some oil with it. A decent penetrant is "Liquid Wrench". Another that is always at the top of the list is PB Blaster"- it has surprised many users with how well it works. Note that when trying to loosen rusty parts, it's important to first remove as much of the rust as possible with a wire brush. Once it's as clean as a wire brush will get it, apply Liquid Wrench, then give the piece repeated light taps with a hammer for ten or fifteen seconds; this helps work the penetrant into the crevices. Wait two minutes, then repeat the Liquid Wrench/tapping procedure. After repeating the procedure 3 or 4 times, ''then'' try to loosen it with one swift blow. Sometimes it won't work, but the majority of the time, your patience will allow you to not only remove the rusted nuts and bolts, but to possibly even reuse them. A longer soak time is better than a shorter soak time, with repeated reapplications if possible. ===Some recommended penetrating fluids=== *Acetone mixed with Automatic Transmission Fluid '''<font size="5"><nowiki>*</nowiki>'''</font> *Acetone mixed with Power Steering Fluid *Air tool oil *BG In Force *[http://www.break-free.com/products/products_breakfreeclp.asp?catalog=civil Break-Free CLP] *[http://www.blueworksbrand.com/products/penetrant/ Blue Works Industrial Grade Penentrant] by WD40 *CRC Industries: **[http://www.crcind.com.au/catalogue.nsf/web_brands/CRC+5-56?openDocument 5-56] **[http://www.crcindustries.com/auto/content/prod_detail.aspx?PN=05002&S=Y Freeze-Off] **[http://www.crcindustries.com/auto/content/prod_detail.aspx?PN=401712&S=Y Knock'er Loose] **[http://www.crcindustries.com/auto/content/prod_detail.aspx?PN=05330&S=Y Ultra Screwloose] *Diesel fuel *[https: //www.lawsonproducts .com/Drummond/Open-and-Shut-Nut-and-Bolt-Loosener-and-Rust-Penetrant/DA6152.lp Drummond Open and Shut]<ref>https: //www.hotrodders .com/forum/best-penetrating-lubricant-147009.html#post1033340</ref> *[https: //www.lawsonproducts .com/Drummond/Open-and-Shut-NutBolt-LoosenerRust-Penetrant/DA7671.lp Drummond Open and Shut]<ref>https: //www.hotrodders .com/forum/best-penetrating-lubricant-147009.html#post1033340</ref> *[http://www.lubecorp.com/products/excel_440_super_lubricant.html Excel 440 Super Lubricant] *[http://www.bilthamber.com/ferrosol.html Ferrosol] *[http://getgibbs.com Gibbs] *GM General Purpose Penetrant and Heat Valve Lubricant #1052627 *Hilco Lube #5035 *[http://www.howeslube.com/products/index.php/category/40 Howes] *[http://justicebrothers.com/pages/products/products_specialty.htm JB-80] *[http://kanolabs.com Kroil/Aerokroil] *[http://www.gunk.com/lubricants.asp Liquid Wrench] *LPS: **[http://www.lpslabs.com/product_pg/lubricants_pg/LST.html LST] **[http://www.lpslabs.com/product_pg/lubricants_pg/KB88.html KB 88] *[http://mousemilk.com/ Mouse Milk] *[http://www.orbindustries.com/penetrants-lubricants.php Nuts Off] *Paraffin wax *[http://pbblaster.com/store/moreinfo.cfm?Product_ID=1 PB Blaster] *[http://www.plusgas.co.uk/ PlusGas] *[http://www.ronsonstore.com/multilube.aspx Ronson Multi-Lube] *[http://www.schaefferoil.com/specialty/190_Penetro.html Schaeffer Penetro 90] *[http://www.seafoamsales.com/deepCreep.htm Seafoam Deep Creep] *[http://www.uchem.co.uk/products.php?section=OIL&type=cat Unilease] *[http://www.wd40.com/ WD-40] *Zep 45 ==='''<font size="5"><nowiki>*</nowiki>'''</font> Commercial penetrating fluids compared to ATF/acetone mix=== Machinist's Workshop magazine actually tested penetrants for break out torque on rusted nuts. They arranged a subjective test of all the popular penetrants with the control being the torque required to remove the nut from a "scientifically rusted" environment. {| class="wikitable" |- ! Penetrant !! Average load |- | None || 516 lbs. |- | WD-40 || 238 lbs. |- | PB Blaster || 214 lbs. |- | Liquid Wrench || 127 lbs. |- | Kano Kroil || 106 lbs. |- | ATF/acetone mix || 53 lbs. |} The ATF/acetone mix was 50/50 automatic transmission fluid and acetone. Liquid Wrench is shown in this test to be about as good as Kroil for about 20% of the price. Info from [http://www.hotrodders.com/forum/a-1558916-singlepost32.html here].
