CRC Knock’er Loose Penetrating Solvent 03020 – [Reddish] 13 WT. Oz., Industrial Grade Penetrating Solvent and Lubricant

I attempted to use this product for the first time this past weekend. When I unwrapped the aerosol I discovered that the application nozzle had broken off during shipment. Unable to use.

Wasted lubricant squirting about trying to insert the plastic "straw" into the head - does not fit! Had to use a straw from another item. Should not be that difficult to include a straw that fits.

it did not work with allowing me to remove my home garden hose that was stock on the nozzle.

no spray nozzle

Everyone seems to swear by some magic penetrating oil or another. I do not, and have tried them all, plus ATF, melted paraffin, bacon fat, cat vomit, Kroil, Mouse milk, whatever.... the most important things for loosening stuck fasteners are: patience, understanding what you’re dealing with, patience, lubrication, heat, patience....etc. Usually one stuck/corroded fastener is different enough from the last that whether or not it comes loose easily can’t really be attributed to this or that oil. This oil seems as good as any, though. Smells good. Price was reasonable and I had to buy something. If I start to have any evidence that it is special, I’ll update this.An update..noticed that it says on the can that it “dissolves rust and other corrosion”. I’m pretty sure this is just a lie. “Dissolve” would mean that the rust goes into solution. It doesn’t mean anything else at all. If rust doesn’t go into solution, like salt does in water, or grease in gasoline, it just does not dissolve. I have been soaking some rust flakes for days. I feel like an idiot doing it, because I knew it would not dissolve, and, no, it has not changed a bit.Rust on stuck fasteners is sometimes ground into a fine powder and mixed into a paste with any grease or oil...this product would dissolve the grease/oil, leaving you with a cloudy, oily mixture, but that is in no way “dissolving” any rust. Whoever came up with this mixture and wrote the label should know better. They probably did know better and chose to lie. If you want to make that silly claim, put some aqua regia in there, but I think you would need a better can, and a better lawyer. (For all the injuries and other destruction that would result.)Update # 2: It is July 18th. I wrote the original review in early May. I check on my little container of this stuff and the rust flakes in it regularly. The "knocker loose" is slowly evaporating. The rust is unchanged in any way. It is NOT dissolving. Again, I just can't believe that the can says "dissolves rust". It does not dissolve rust, so don't say that.

Product works good and can remove some rust in some cases but is not like the show on TV on or internet is not all that of a Product.

The price is to high it works ok
