So, wadja pick?
When we first went into the soap business I wanted to use Soapy Sales, but it turned out it was already being used.
I don’t remember what else we thought of, except The Soap Bar. (We’re a brick and mortar business.)
Good luck.
Ralphy’s Favorite Christmas Soap
Well, I sent in ten puns, hoping one would win… but sadly, no pun in ten did. 
Thank you, thank you, and I got an extra day to think up a name. I left some samples, but the owner wasn’t in today, and I need to show her my display, etc. The manager thinks it’s good, though.
Keep 'em coming! Mr. Stasaeon is particularly fond of “Lather is the best medicine”, but we’ve been laughing ourselves silly over some of these contributions. Soap Benedict - HA! I am slain.
In Ballard, “Soap Springs Eternal” and “Dirty Mouth” are the only feasible choices so far. Think Archie McPhee.
(Personally I’m partial to “Holy Foamin’ Empire,” if only it reminds me of a travel website I wanted to start: “Wholly Roamin’ Empire.”)
Soap Floats
The Soap Must Dye
Let Soapy Dogs Lye
Soapendous
Film at Eleven
Soapmobile
Scrubs (or some copyright-indulgent variation: Scrubz, Skrubz, etc.)
Clearly I’m not much of a cunning linguist. I’ve got:
Sudsational
I’d Lather be watching my Soaps
No place like Foam
Soapy words that I was using:
Soap, Lather, Lye, Suds, Rinse, Clean, Squeaky, scrub, deterge, foam, froth, effervescence, slippery… that’s about all I can come up with.
Mindfield: Ah Thrills. Their motto: “It tastes like soap!”. Which is how you describe it to people who haven’t tried it, and what they invariably say regardless when they eventually do.
E. Thorp: Film at Eleven: I don’t get it… no… hmm… wait, I think I… booooo! 
Final contenders, after my husband and I meticulously sorted through (and there were so many damn good ones):
Film at Eleven (I* howled*)
Lather is the Best Medicine
Soap Rings Eternal
and, oddly, back in the running,
Lyer, Lyer
Mr. Stasaeon is leaning towards Lyer, Lyer, because it is short and easy (like my last boyfriend! Ba da bum crash). He keeps tripping over Lather is the Best Medicine, as he keeps trying to say laughter, naturally. Bit of a tongue-twister. He wonders if soap rings are something I want to promote. But hey, as **E. Thorp ** points out, this is Ballard. We’re into the weird. *Film at Eleven * might go over people’s heads a little, or be mistaken for another type of shop. I soap-ose (ar! ar!) that’s the beauty of it.
You guys are friggin’ awesome. I knew I could count on the Dopers for cleverness. 
Is it too late to suggest “Bar None”?
If all the world were enrolled at the SDMB, you’d have to go with Soapiness Ensues (with the accent on the second sytllable of soapiness, of course). Of course, you could eventually market some appropriately-shaped novelty foamers under that name…
Is it too late to suggest Opera Soap?
Do these suggestions have to be clean?
Anyway:
The Darling Suds of May
Foam, Sweet Foam
Bar One
Soapageddon, bringing an end to dirt as we know it.
What about “Jailtime Aphrodisiac?”
I can’t believe that no one has suggested The Straight Soap.
How about:
Lather Bar
Not on a Rope
Welcome Foam
Quantum Foam
Foam Sweet Foam
There’s No Place Like Foam (I know, too wordy - had to do it, though)
Soap-a-rific
S.O.P.
or
Soap-isticated?
:smack:
I was gonna go with Don’t Drop 
And since you’re in Ballard, maybe it oughtta be Foam, Swede Foam.
And I was going to go with “Ben Dover: Worth Picking Up!” 
Good one! (For those who missed the discussion.)
I like “Soap du Jour.” I was going to suggest “Soapy Sales,” but that’s already been done.
Soap 'N Attem.
Like Suds through the Hourglass.
Sure Does.
Welp, folks, I’ve made the placard and it says:
Lyer,
Lyer
Soap by [me]
yada yada
Made in Seattle
[phone number]
Impressive, huh?
Sorry - stuck with the original. I loved, loved, loved all of the suggestions, and I thank everyone for their help. It was a lot of fun, and I’m glad for your contributions, as they helped me out enormously. It was really close by the end of it, between Lyer, Lyer and Lather is the Best Medicine. And I was really hot for Soap Benedict or just plain Holy Foamin’ Empire. After consulting with my co-workers, the scale tipped in favour of Lyer, Lyer, and so it is.
Thanks, Soapers.
