Hi all!

Have a question about cleaning of porous wall in small bakery. The wall of process area made from limestone. The area is dry. But premises had another destination in past (canteen). According legislation the wall must be cleanable and washable. Also it must be waterproof. What you think about cleaning procedure with hoower? Is it possible? Thank you.

I worked in a facility that was originally built off of a 1880's farmhouse that had a stacked field stone wall in the mixing kitchen. We framed it in and covered with FRP board to ensure it was cleanable. It might be the best option for you to comply with regulations.

FRP would be an option, as long as the joints do not cause an additional problem.

 

Maybe a good two part epoxy paint made for marine environments?

Thank you answers, colleagues. But our company rent this premise. And stackholders don't want invest any significant money to it. Also they don't want any troubles with owner of premise. So there is a task - get away with it :)

Of course you can get away with it, provided that your auditor doesn't write you up for it :)

 

You didn't say what standard you're using so is this just a GMP audit or is it a GFSI level audit?   Look at the audit criteria closely and see what it says and be able to answer to an auditor about it.  I would test different cleaning methods on the wall, find one that makes it look pretty clean, and then put that SOP in writing with a note along the lines of:

 

Cleaning procedure is designed to leave wall clean and dry.  Although wall is porous, water does not penetrate it or cause an additional food safety concern and the wall is cleanable and washable by following the steps in this procedure.  

 

If you wanted to go one step further, do some APC or ATP tests on the wall to validate that your sop is effective in making it a clean surface.
