PB Blaster WARNING !!

[Maine Sail]

Hi All,I thought I sould let you all know that I discovered, the expensive way, that you should never use PB Blaster near ANY engine or transmission seals.I needed to remove my shaft coupling so I sprayed the four bolts with PB Blaster, thinking nothing of it, and let is sit over night. Evidently some of it dripped onto my transmission output seal and when I went to the boat he next day the majority of my transmission fluid was in the pan and not the transmission.My transmission is a 2003 ZF v-drive and had never, ever leaked a drop. After speaking with a few mechanics about this they know the problem well. PB Blaster can eat engine seals, transmission seals and plastic cups! Keep this stuff far away from any output shafts, engine seals or seals you don't wan't leaking.PB Blaster is great stuff but very dangerous to the tune of $800.00 on my transmission. Use it with caution!

WOW!! Who would have thought?

Is there a warning on the can? I'm going to go and check my can right now.

YIKES

I've used this stuff before and it works great for breaking free old stuck on bolts and such. Now I know why.

I love PB Blaster, thanks for the warning.

I've soaked car weatherstripping in it to make it more pliable before. Did a great job, but it grew about 50% in size. Probably the same problem you had with your seals. Used it around my car engines without problems, maybe just lucky, though

Thanks - good info

That reminds me of a mosquito lotion made locally up here -- If you don't wash your hands after putting it on it melts your car steering wheel. It does keep the bugs away though, and PB Blaster will losen up a nut.

Very Useful Information

I switched from WD-40 to PB Blaster years ago to free up everything!! I never thought that this stuff was so distructive on seals. I thought it was just a very fine penetraint, but if its eating rubber seals it must have caustic properties. Sorry we learned of this through your misfortune, but I find this information extremely useful and will proceed with caution in the future when using PB Blaster!ThanksBobCatalina 30 Breezin II
