USAGE GUIDE
How to use Derek
Preparation and Lubrication
Clean before first use
Wash Derek with warm water and mild unscented soap. Rinse thoroughly and pat dry. Platinum silicone is non-porous and won't harbour bacteria when cleaned properly.
Use water-based lubricant only
Always use water-based lubricant with platinum silicone toys. Silicone-based lubricants can degrade the surface texture over time.
Apply generously
Apply lube to both yourself and the product. More is always better. The Sil-Slide outer layer responds beautifully to adequate lubrication.
⚠️ Never use silicone-based, oil-based, or petroleum lube with silicone toys. Water-based only.
Using the Suction Cup Base
Choose a smooth, flat surface
The suction cup works best on non-porous smooth surfaces — bathroom tiles, glass shower walls, mirrors, or smooth floors. Textured or porous surfaces won't create a strong seal.
Wet the surface slightly
A small amount of water on the surface before pressing the cup down creates a stronger vacuum seal. Press firmly, twist slightly, and test the hold before use.
Harness-compatible
Derek is also compatible with most O-ring harnesses. This makes it suitable for strap-on use for all genders and body types.
Cleaning & Storage
Clean after every use
Wash with warm water and mild soap immediately after use. For deep sanitisation, platinum silicone can be boiled for 3 minutes or placed in the top rack of a dishwasher (no detergent).
Dry completely before storage
Pat dry with a clean lint-free cloth. Ensure it's fully dry before storing to prevent any moisture build-up. Air dry for 10–15 minutes after wiping down.
Store in the included pouch
Store Derek in the satin storage pouch included with your order. Keep away from other silicone toys (silicone can bond with other silicone), and store at room temperature away from direct sunlight.
Temperature Play
Warming Derek
Place in warm (not boiling) water for 5–10 minutes before use. The platinum silicone retains heat beautifully, adding another dimension of realism to the experience.
Cooling Derek
For a different sensation, place in cool water or the refrigerator (not freezer) for a few minutes. Always test temperature on your inner wrist before use.
⚠️ Never use microwave or direct heat sources. Always test temperature before use.
