2 – Hydrate your PET-1 Guitar Humidifier

  • Remove the plastic fastener holding the PET-1 together.
  • Gently manipulate the outer shell allowing the polymer core to move toward the center of the PET-1, making sure none of  the polymer is near either end.
  • Using clean tap water, fill a container that’s large enough for the PET-1 to lay flat. Submerge for approximately 25 minutes.
  • Rest for 10 minutes. This will allow the polymer to absorb any residual water, safely locking it into the core as a solid.

3 – Dry your PET-1 Guitar Humidifier

  • Gently dry the monofilament outer shell with a cloth.
  • The polymer core is a hi-tech absorbent– not a sponge. Do not squeeze or wring out the PET-1 when handling. Excessive pressure can cause the polymer to extrude. Rarely, extrusion can occur on first hydration. If this happens, wipe away residue. 

4 – You’re done! Now you can start humidifying!

  • Insert the PET-1 into the sound hole of your guitar, and humidify while you play.

5 – Removing and rehydrating your PET-1 Humidifier

  • Over time the PET-1 will shrink back in size, indicating that it is time to rehydrate.
  • Remove by turning your guitar upside down and gently rotating the body until the PET-1 appears at the sound hole.
  • Remove the PET-1 acoustic guitar humidifier and rehydrate.
  • For simple recharging, we recommend you own 2 PET-1 guitar humidifiers, where a pre-charged guitar humidifier stored in a sealed container and can be swapped out and back into your guitar for constant humidification.

It’s simply the best guitar humidifier money can buy. Better still, it’s born in the USA, and backed by a lifetime guarantee.

WHAT NOT TO DO

  • Do not squeeze or wring out the PET-1 when handling. Excessive pressure can cause the polymer core to extrude and may void your lifetime guarantee.

The PET-1, although simple in its design uses high technology materials and as such should not be used in the same way as other instrument humidifiers on the market.

The polymer core consists of a set of polymeric chains that are parallel to each other and regularly linked to each other by cross-linking agents, thus forming a network. When water comes into contact with one of these chains, it is drawn into the molecule by osmosis.

Water rapidly migrates into the interior of the polymer network where it is stored as a solid.

This is why you need to rest the PET-1 after soaking in water, to allow the water molecules time to lock together with the polymer creating a solid that will not harm your guitar.
