Look at the product label to make sure you’re using the right kind of stain remover for the type of stain you’re treating. Follow the stain remover instructions to figure out how much to use and how long to leave it on the stain. If the stain remains after the first pretreatment, try brushing more of the stain remover directly into the stain. [3] X Research source
The water temperature you use for presoaking depends on the type of stain. Generally, protein-based stains such as blood or water-based paint should be soaked in cold water. Dirt, mud, and grass stains tend to respond better to warm or hot water. [5] X Research source Depending on the type of stain, you may choose to add a stain treatment such as non-chlorine bleach to the water before you place your gi in the water to soak. Check the label of the product to make sure you’ve got the right kind of stain fighter, and always follow the instructions on the product label. [6] X Research source Your washing machine may have a “soak” cycle you can use for presoaking your gi. Many washers, especially front-loaders, don’t have a “soak” cycle. If your machine does not have a “soak” cycle, try letting the machine fill up with water and then stop the cycle temporarily. [7] X Research source You can also use a large plastic bucket or even a bathtub to presoak your gi. [8] X Research source
If there is no cold water setting on your washer, choose the coolest water temperature available. The jacket of your gi may have a stiff collar with rubber inside. Hot water might cause the rubber inside the collar to become misshapen.
Even if your gi is white, chlorine bleach can remove color from any embroidered patches on your uniform. If your white gi is a cotton-polyester blend, chlorine bleach may cause yellowing with repeated washings. [11] X Research source
Avoid fabric softener, which is added after the rinse cycle and can cause an undesirable residue to remain in the material of your gi. This residue can make clothing less absorbent and prevent it from wicking away moisture. It can also extend the drying time for your gi. [13] X Research source
Avoid drying your clothes in a damp area. Although air-drying is gentler on your gi than tumble-drying, persistent dampness can encourage the growth of mildew on your gi. [15] X Research source If you use a drying cabinet, select the lowest heat setting possible. Do not tumble-dry your gi. The tumble action of a mechanical dryer will wear out the fabric of your gi more quickly than air-drying. Tumble-drying can also make the fabric more prone to tearing. [16] X Research source
