I've had similar experiences with Bio-Blast myself. Can't say warming it up ever did much for me either, but I agree wholeheartedly about patience being key. It's definitely not the quick fix WD-40 is, but if you give it enough time to penetrate, Bio-Blast seems to break down corrosion and grime more thoroughly. I've seen it loosen fittings that WD-40 barely touched after multiple attempts.
As for shaking the can—you're onto something there. Bio-Blast has a tendency to separate slightly if it's been sitting around for a while, especially in colder environments or storage areas. Giving it a good shake helps remix the solvents and active ingredients, ensuring you get a more consistent spray pattern and better coverage overall. I've noticed this particularly when working on older plumbing fixtures or stubborn valves. It might seem minor, but proper dispersion really does make a difference in how effectively the product penetrates tight spaces.
One other tip I'd add from experience: angle matters quite a bit too. If you're spraying upward into tight fittings or hard-to-reach spots, try using one of those flexible straw attachments (the ones that come with some cans or aftermarket ones). It helps direct the spray exactly where you need it without wasting product or making a mess everywhere else. Learned that one the hard way after soaking my sleeve more than once...
In short, you're not imagining things—shaking definitely helps, and patience plus proper application technique usually beats out quick fixes in my book.
I've definitely had my fair share of soaked sleeves too... learned pretty quick to keep some old towels handy whenever I'm messing with plumbing sprays.

Glad you mentioned this—thought I was just imagining things when my Bio-Blast seemed less effective after sitting in the garage all winter. Shaking it up made a noticeable difference for me as well. Also, your tip about the flexible straw attachments is spot-on. I picked up a cheap pack online last year, and they've saved me from all sorts of awkward angles and messy overspray.
Patience really does seem to be key here. I admit, sometimes it's tempting to just blast everything with WD-40 and hope for the best (especially when you're short on time), but Bio-Blast has surprised me more than once when I've given it enough time to work its magic.
Speaking of patience, I've noticed Bio-Blast works great on minor clogs, but for tougher blockages, it hasn't always done the trick for me—even after shaking it up. Ended up having to snake the drain anyway. Curious if anyone's tried pairing Bio-Blast with other methods (like plunging or hot water flushes) and found a combo that consistently works better...

I had a similar issue last spring when our kitchen sink kept backing up—not fun. Bio-Blast helped initially, but like you, I hit a wall with tougher clogs. What worked best for me was combining Bio-Blast with a hot water flush afterward. I'd pour the Bio-Blast down, let it sit overnight (seemed to give the enzymes more time to work), then follow up in the morning with boiling water. I think the heat helps loosen up grease deposits that enzymes alone might struggle with.
Still, there was one stubborn clog where even that combo didn't cut it. Ended up borrowing my neighbor's drain snake and realized it was a compacted mess of coffee grounds and grease—lesson learned about what not to send down the disposal...
Anyway, since then I've made this enzyme-and-hot-water flush routine a monthly preventative thing, and it's been pretty smooth sailing so far. Might be worth giving it a shot regularly rather than only when problems pop up.
I've had mixed luck with Bio-Blast myself. Last year, our shower drain was acting up—standing ankle-deep in water isn't exactly my idea of a relaxing morning routine. Tried Bio-Blast overnight, and it helped a bit, but didn't fully clear things up. Ended up doing the hot water flush trick too, and that combo definitely improved things.
Funny enough, I also discovered the hard way that hair and soap scum can form some kind of indestructible super-material...had to pull out a nasty clump with one of those cheap plastic drain sticks (gross, but oddly satisfying).
Since then, I've been wondering if regular plunging after enzyme treatments might help keep things clearer long-term. Has anyone tried plunging regularly as preventative maintenance, or is that just overkill?
