    Question Mold on leather bag

    Hello all. So I have this leather bag for many years now. The mold started showing not long after I had the bag (about 2 years) and I had since tried to do self-cleaning with mild soap twice and the mold came back. So finally 2 years ago, I sent it for professional cleaning and colour restoration. It was okay for a while and I made sure to keep the bag in a dry and cool environment. However, after about half a year, the mold started showing again.

    So, I would like some advice if it is still possible to salvage the bag or if i should just discard it?

    Thanks a lot in advance

    >>> The mold started showing not long after I had the bag (about 2 years)

    It is common to have leathers in storage that are infested with mold starting from the tannery all the way into our modern home. The leather is preserved against mold with fungicide and as fungicide weakens after a few months, mold presents itself when the environment is humid and lacks sun or UV lights. Fungicides only prevent and preserve the leather from infestation and if the mold sinks its roots into the leather, any further application will not remove the sinking roots.


    >>> and I had since tried to do self-cleaning with mild soap twice and the mold came back.

    Mild to the leather means cleaning with a pH value of 3 to 5. Any pH value that is above 7 will be harsh to the leather. Remember leather is an amphoteric protein material and even any alkalinity specialty cleaner will need to be neutralized with a low pH rinse like Acidifier-2.0 (pH value 2.0) to bring back the final pH value of the leather to between pH 3 and 5. All soaps will leave a scrum that sticks to the leather similar to our bathtub's coats with sticky soap scum. These soap scum become soiling for the mold/fungus to flourish and multiply too. Humidity also plays a part and above 55% percentage of moisture contents also flavors mold/fungus infestation. Keeping leather away from sunlight/UV light also attracts mold/fungus growth.

    If the leather is not treated with tannery quality mold inhibitors such Leather Doctor LeatherMoldOdorInhibitor-3.6 before refinishing and with a periodic 8 monthly application until the mold/fungus dormant pores are complete eradicated, mold/fungus may re-appear.

    Leather in tannery storage is often infested with mold/fungus when conditions mentioned earlier favor their growths. What they do is clean off the surface growth clean and treated with similar products of the same quality as LeatherMoldOdorInhibitor-3.6
