Buying advice

When choosing a defogger, consider your sensitivity to chemicals, typical dive duration, and budget. For occasional use, DIY methods like baby shampoo suffice, while frequent divers may prefer long-lasting sprays or gels. Ensure the product is safe for your mask's lens coating (avoid alcohol on certain coatings).
