The Pro Clean Concentrate is very suitable for removing stains from clothing. The fresher the stain, the easier it is to remove. If the stain has dried up, soak it for longer if necessary. Then put the garment in the underwear as normal, according to the recommendation in the textile.
Note: If necessary, check for colour fastness.
You will have a lot of fun with the good results. The Pro Clean Concentrate also neutralises odours in a very pleasant way.
