Rust penetrants ?

[Lager]

My go 2 brand has always been PB Blaster, its served me well for the past 40-50 years of working on customers cars. But, since I now work an a Autozone parts store I noticed a number of local mechanics coming in and buying the Seafoam Deep Creep product. These guys claim that it works better then the PB so I just bought a can to give it a try. Just tonight I gave some rusted bolts a shot of the Seafoam and noticed that it sort of stuck to the bolts better and foamed up instead of just running off like the PB does and it also smells better, not like I give a darn about that. Also included in the photo is a new filter that I bought from Autozone and noticed that the " Made in China" is proudly displayed when it used to be in really small lettering. Your thoughts?

Kroil is still my top for really stuck stuff but its kinda pricey and I use pb blast majority of the time just cause its cheaper.

I haven't used either of these products.

Kroil has been my go to.

Kroil has been my go to for the last 30 years. I've found nothing better

Most of the professionals I know use Kroil.
As a homeowner doing homeowner stuff, I occasionally have to break out the propane solderimg torch, but PB Blaster has done everything I need it to 95% of the time.

Deep Creep works well, better than pb blaster. I always keep a can on hand.
Wurth is good stuff, but it's higher priced than Kroil.

If you want to eat the rust use kroil.

Like many I use Kroil also, recently bought a can of Free All. I use it more as a bore cleaner than a penetrant tho.

I buy PB by the case for general use. For the really tough situations, I break out Blue Creeper and sometimes Kroil. I also have some FreeAl in the shop.

Blue Creeper is the best that I’ve ever used. It seems to wick deeper into the joint.

When all else fails, I break out the hot wrench….
