I'm Peter Reinhart! Ask Me Anything! Monday, February 15, 2016 7:00-8:00 pm EST

To kick off our AMA feature, we have invited author, chef and master bread maker and host of Pizza Quest, Peter Reinhart, to be our first host! Peter will be in the Forum on Monday, February 15th, from 7:00 - 8:00 pm EST. If you are unable to be online during the live session, you can post your questions in the sticky post. Peter will answer those questions during the live session on February 15th. You can view Peter's answers to your questions as well as what happened during the live session in the session thread.

Ask Me Anything New Forum Feature

You will notice a new forum at the top of the main page called, "Ask Me Anything". This forum will be used for live one hour "Ask Me Anything" (AMA) sessions hosted by people who are knowledgeable in different areas pertaining to wood fired ovens. How it works:
- Each AMA will have a "sticky" thread where the community can post questions they would like answered during the live session. This will allow everyone to participate even if you can't be online for the live session. These questions will not be answered by the host until the live AMA; if you need an answer quickly, you should post it in the appropriate Forum area for the community to respond.
- Another thread will be posted for the live AMA. Registered users who are logged in during the live session can interact with the host by asking questions and receiving responses.
- The live thread will remain in the AMA forum to view after the session.

We hope you enjoy this new feature! Please let us know if there is a topic that you'd like to have as an AMA and we'll look for a host!

      If it is fairly new mortar use a 50/50 solution of muratic acid and water. Wear gloves and eye protection. I use a brush and have the hose handy to rinse. Just occurred to me inside or out? The hose for rinsing may be an issue...

        Inside you can use a wire wheel attachment for a drill or angle grinder. Use one made of brass.

        EDIT: for dry cleaning brick inside the dome.

            I thought the ratio is 10% acid to water?

              10 to 15 parts water to 1 part acid unless you want to burn out your eyes, your lungs and the brick.

                It depends on the type of brick, but that is pretty close. But typical cleaning should be around 1:6 - 1:10.

                  Also you will need to pre-wet your brick before applying acid.

                    Re: Cleaning mortar from bricks

                    F'ing around with muriatic is not something I recommend to anyone, it is a 30 percent solution of hydrochloric acid and is a serious industrial chemical. If you insist on using it, hose down the entire area until fully saturated, dilute to a reasonable mix (10 to 15 to one) by pouring the acid into the water and wear appropriate safety equipment.

                    There are available proprietary cleaners that are a little safer, Sure Klean 600 detergent is one, although it is still a dangerous product. If you are not able to keep from making a mess while laying your masonry, then you can use industrial strength vinegar to remove minor amounts of mortar.

                          Just sponge water over it.

                              Other than something breathable like Thoroseal, using paint or lacquer to masonry is a death sentence. Never apply anything over masonry that keeps it from breathing.
