never use massage oil or hand cream as lubricants with your LELO. Always clean your LELO thoroughly before and after each use. The most effective way of doing this is to use a purpose-made cleaning solution such as LELO's Antibacterial Cleaning Spray. Alternatively, you can wash the silicone with warm water and antibacterial soap, rinse with clean hot water and pat dry with a lint-free cloth or towel. Never use cleansers containing alcohol, petrol or acetone. Your LELO is 100% waterproof and submersible to a depth of 1m. The open charging socket is sealed from the internal workings of the massager, so can be cleaned and used underwater freely. Avoid leaving your LELO in direct sunlight and never expose it to extreme heat. Store your LELO in a dust-free place and keep it away from toys of other materials. For Adult Use Only. Those who may be pregnant, have a pacemaker, diabetes, phlebitis or thrombosis should consult with a medical professional regarding the risk of blood clots before using any personal massage product. Avoid using a silicone-based lubricant as this could make the silicone permanently tacky. If you wish to use a silicone-based lubricant, perform a patch test first. Store in a cool, dry place and avoid exposure to direct sunlight for years of enjoyments. Avoid excess heat. Remember to read all directions on the enclosed manual.
