PB Blaster Lubricant

[noe-place]

I can't recall the gentleman's name but I had to post a note to thank him for saving me some money. Both my black and gray water valves had become very, very hard to pull out to dump the tanks so I asked the RV Net members for advice. An enterprising member suggested I try PB Blaster which I found at Lowe's. First application didn't produce great results so I waited a bit and sprayed them again and they began to loosen up a bit. By the third application they are opening and closing just like new. I'll be keeping a can in my RV from now on.

This is so true, but it is hopeless trying to convince people here.

Thought WD 40 was the miracle spray until I used PB Blaster. it eats at the corrosion. I find after spraying it's best to let it soak for a while. The longer the better. i keep a can in the shop an one in the camper.

Same here - WD40 is much milder. If you have a little patience it is amazing what PB Blaster will loosen up.

While PB Blaster is great for freeing up "STUCK THINGS" and yes some need time and several applications even over several days to get the job done, I don't think it's good as a lubricant and you should follow up with an actual lubricant once the item has been restored to its functionality.
