Which Rust Removal Products Brand Wins?

not much visible progress at 24 hours despite the liquid clearly showing dissolved rust; by 1 week described as working faster than molasses; by 2-3 weeks performing very well, close to molasses

very effective and fast from the first 24 hours ('attacking the rust with a fury'); by 3 weeks showed deep pits not just on the end but along the sides of the bolt, indicating it was eating into good metal, not just rust

modest progress at 24 hours; by 1 week described as giving a better result than molasses at that point; by 2-3 weeks described as doing an amazing job, continuing to wick up the side of the spike and remove additional rust

modest progress at 24 hours; by 1 week described as performing about the same as white vinegar; at the 2-week mark the narrator remarks it 'appears that the apple cider vinegar is working the best so far'; by 3 weeks described as doing an amazing job completely removing rust from the exposed area

did not appear to attack or damage the metal flakes, stayed clean

dissolved almost entirely, the most aggressive of all products on the metal flakes

dissolved pretty much all of the metal flakes within 24 hours, and totally dissolved them by 1 week, leaving mostly foam

dissolved almost all of the metal flakes, similar to white vinegar, with very little left by the end

significantly damaged the paint; described as destroying the paint with visible paint flakes coming off by 1-2 weeks, and having lost nearly all of its paint by 3 weeks, despite being marketed as safe on painted metal; narrator speculates the paint contained some type of metal that reacted with the product

surprisingly did the least damage to paint of all the products tested; narrator states he expected more damage given how strong the acid is

significant paint damage, described as flaking off starting around 1 week and by 3 weeks bubbling up and peeling off in a big sheet

at 1 week, some flaking was noted but described as not as bad as Evapo-Rust or white vinegar at that point; by 3 weeks, described as having totally removed all of the paint, ultimately as damaging as the other paint-stripping products

no corrosion or damage observed

just about totally dissolved the aluminum, described repeatedly as leaving it 'very thin', by far the most damaging product on aluminum

very little to no corrosion observed

some staining observed but no more corrosion noted than molasses or white vinegar

very close to molasses, one of the two lowest metal-loss results of all 5 products

removed the most material of all 5 products, confirming it clearly ate away some good steel in addition to rust

removed nearly twice as much weight as molasses and Evapo-Rust, a likely indicator it ate into roughly 2 grams of good metal in addition to rust; also climbed furthest up the landscape spike of any product, removing extra material via wicking

grouped with white vinegar as removing nearly twice the weight of molasses and Evapo-Rust, likely including roughly 2 grams of good metal; also noted to have climbed the landscape spike removing extra material via wicking, similar to white vinegar

at 24 hours, described as having done 'a much better job' than molasses at that point

cleaned rapidly, reaching bare clean metal in some areas within 24 hours
