This is a great quality UV light - compact and relatively powerful!
I use it as a stain remover. UV is effective for some stains such as curry (turmeric) and also tomato based sauces which proves very difficult to remove. I've found that if you expose these stains to sunshine within several hours it will remove them completely. Sunshine isn't always available when or where I need it and this torch works for that purpose perfectly. For a small spot, 5 to 10 minutes and the stain is gone!
