Sodium bicarbonate
Always remember to test the bicarbonate on a small area of the mattress before using it on the entire surface, to check that it does not cause any damage to the fabric. In fact, some fabrics may not tolerate this ingredient and may become damaged.
We recommend that you repeat the procedure numerous times until you get the effect you were looking for. Sometimes this remedy turns out to be ineffective for the simple reason that it is probably too late to renew your old mattress.
