Simply use a mild detergent, avoid bleach or fabric softeners, and wash on a gentle cycle. This preserves conductivity and ensures the sheet lasts as long as a standard bedding set.

For best results, the outlet’s ground port must be functional. Most modern homes have grounded outlets, but if you’re unsure, you can use a simple outlet tester (inexpensive at any hardware store) to confirm. No ground port? An electrician can install or fix it quickly so you can sleep grounded with peace of mind.

Yes. Distance from the actual ground doesn’t matter as long as the grounding cord is plugged into a properly grounded outlet. The Earth’s conductive path through your wiring remains effective, even many floors above street level.

It’s fine to use an extension cord, provided it’s grounded. Look for a three-prong cord (with the round grounding pin) so the grounding connection remains intact. This ensures the Earth’s conductive path isn’t broken, even if your bed is not right next to the wall outlet.
