So I was at the MotoGP in Indy. I left my helmet with gloves inside the helmet in what I thought was a dry place. However, it was not. Therefore, I got some mildew on both. Luckily the smell in the helmet is not as bad as the gloves. I’ve been dealing with the smell for a little and can’t take it any more. I was looking for cleaning recommendations. I think for the glove I’ll go soap and water, then a leather treatment. I could use help on what treatment to use. For the helmet, I don’t have any idea. It’s a Suomy helmet if the type of padding makes a difference.
