Ring around the carboy

So, brewed a batch a couple weeks ago, and after four weeks in the carboy, my FG numbers stabilized and I bottled.

There's a ring around the inside of the carboy where the beer was, and it's pretty dry and crusted. I soaked in water for a few hours (with a fair dose of liquid dish soap) and scrubbed best I could with my carboy brush...

And the crust is still there.

Any ideas on how to clean it? Soak longer? Get a stiffer brush? Some sort of flexible yet rigid hose adapter I can use to blast it ala a pressure washer stream?

Hate the idea of putting a new batch in a vessel with visible residue, even if I soaked in sanitizer (I use Iodine and water), and hate the idea of throwing a 6.5 gallon carboy in the trash (well, the recycling bin, but you get the idea...)

Thanks.

Is it glass? Oxyclean free or PBW soak and the brush should take care of it.

Walmart has a version of this, can't remember what it is called.

One scoop into your carboy, fill with water, let sit for 2 or 3 days, hose out.

For one i would of not used the liquid dish soap, i dont use it on anything that touches beer. (growlers, glasses, carboys, kegs)

If you cant reach it with a rigid brush then let it soak longer with a hot bath.
Sometimes salt works as an abrasive...or oxyclean!

Seems that Oxyclean is the consensus. I'll give it a go.

Thanks, everyone.

I use 4 scoops. Comes off in 30 minutes. Rinse well.

Do they not keep it with the other laundry detergent products? I have never been able to find it in the WM stores around here.

Do not use dish soap. If you can't find the oxyclean, use bleach and let it soak overnight. It will come off.

I never put dish soap in anything I brew with, I got that advice from MrB and followed it from the beginning. But I wash my beer glasses with it... I'm not worried about flavor since it isn't fermenting, like with my brewing equipment, but I've heard it can ruin head retention, right?

So what should I clean beer glasses with? PBW or Oxi? Do you guys do your dishes with that stuff?

Off optic, but I use powdered dish soap in my keg/carboy washer. Never had any issues with head retention, or off flavors.

But in this case I would follow the advice of others and give it a soak with oxyclean.

Be sure to get Oxyclean FREE, as it has no dyes, perfumes, etc.

I use this all the time. But do not leave in a sight glass made of polyemer. It will unwinds the hexial coils!

This is Walmarts brand. It doesn't say "perfume free", but I believe it is. Anyhoo, I've been using it for a long time and it works great.

Hmm... I'll have to look for it again.

I use the target oxycleaner....it's also free of everything and cheap

I have used the Sun as well. It is cheaper when you can find it.

I just run mine through the dishwasher with the rest of the load. Then before I pour a beer with a glass from the cupboard, I give it a quick rinse with cold water from the tap.

I am not sure why this matters. I have used the standard "versatile" oxyclean forever and never had any negative results.

A friend if mine does, too. He makes award winning beer, but..... I just can't bring myself to do it. I'd like to though so I can buy the big box.

Don't be afraid. You have to thoroughly rinse it either way. Admittedly I now use PBW as it works better. But every once and a while I will need to strip a bunch of labels off bottles and the versatile does just fine
