What do I do if I don't have any access to borax?

Depending upon the fabric, use mild soap, with no moisturizing ingredients added, such as aloe, shea butter, coca butter etc. Use a baby toothbrush to gently scrub. If you can, put the fabric in the washing machine with vinegar, and wash on gentle cycle in the hottest water allowed for the fabric. You may have to repeat. If the item cannot be washed - chair or sofa - blot, or rent a rug cleaning machine. Regardless of method or product used, always test a small spot for colorfastness in an area that will not be noticed. Use the hottest water it can take first.
