Wisedry ColorDot Desiccant Instructions: Recharge & Reuse

Quick answer

Wisedry ColorDot packets turn pink when they need recharging

Use ColorDot desiccant packets in enclosed spaces such as camera bags, safes, storage boxes, tool cases, closets, RVs, or boats. When the indicator dot changes from blue to pink, recharge the packet; if the color is unclear, confirm by weight.

Question	Best next step	What to check
How many packs should I use?	Match packet amount to the size and seal quality of the enclosed space.	If dots turn pink quickly, use more capacity or improve the seal.
When should I recharge?	Recharge when the dot turns from blue to pink.	If the dot is only slightly pink, weigh the packet for confirmation.
Microwave or oven?	Use the page tables for timing; shorter repeated cycles are safer than overheating.	Follow the THIS SIDE DOWN sign and keep the dot side up.
When is recharging complete?	Stop when the dot returns to blue or the packet returns close to its original dry weight.	Let the packet cool fully before the second cycle, reuse, or storage.

Safety note: packets become hot after reactivation. Keep them away from children, pets, bare hands, and heat-sensitive surfaces until fully cooled.

ColorDot Desiccant FAQ

What does it mean when the ColorDot turns pink?

A pink indicator dot means the packet has absorbed moisture and needs reactivation. If the color is only slightly pink, weigh the packet to confirm saturation.

How do I double-check saturation by weight?

Use a scale and compare the current weight with the original dry weight. The page notes that a packet gaining over 30% of its original weight is saturated and should be reactivated.

Can I microwave ColorDot desiccant packets?

Yes. Follow the microwave table for your packet size, microwave output, and number of packets. Do not pile packets, and follow the THIS SIDE DOWN sign with the dot side up.

Can I recharge ColorDot packets in an oven?

Yes. Use the oven table on this page, place packets on a wire rack when possible, and heat at 150°C / 300°F according to the packet size and quantity.

Why does the dot change speed vary?

The absorption duration varies with humidity and the enclosed space. A faster blue-to-pink change usually means the space is more humid, opened more often, or needs more desiccant capacity.

Should packets cool before reuse?

Yes. Packets are hot after reactivation. Let them cool fully before the next heating cycle, before handling, and before placing them back with stored items.

How Many Packs Should I Use?

Wisedry ColorDot Desiccant Packet is a moisture-absorbing option for enclosed spaces.

• Absorption Capacity: One pack can absorb moisture up to 35% of its weight!
• Recommended Usage:
  • Small to Medium Spaces (e.g., camera bags, shoeboxes, jewelry boxes): 200g will do the trick!
  • Medium Spaces (e.g., safes, guitar cases, storage bins): 300-500g is ideal.
  • Large Spaces (e.g., wardrobes, tool sheds, RVs, boats): Adjust based on size—typically 1000-2500g.

When to Reactivate

With use, Wisedry ColorDot Desiccant absorbs moisture from the air and loses its drying power. To make it active again, you’ll need to remove the absorbed moisture by heating it.

Color: When the indicator dot turns from blue to pink, a packet is saturated and requires reactivation.

* If it is slightly pink, use the following weighing method to determine saturation.

Double Check by Weight: If the color indicator becomes less responsive, use a scale to check the weight. This provides a more accurate measure of moisture absorption than visual cues alone.

When a packet gains over 30% of its original weight, it is saturated and requires reactivation.

Kindly Note: Due to product properties, the absorption duration varies with humidity. The speed of the indicator dot changing from blue to pink does not reflect product performance. It is recommended to use the weighing method to determine the saturation level if you are unsure.

Reactivate by Microwave

Reactivation time varies depending on the type of microwave, the amount of packets, and the saturation level.

NOTE

• Before reactivation, read the “When to Reactivate” section to ensure the packets are saturated and avoid overheating damage.
• When reactivating, strictly follow the “THIS SIDE DOWN” sign on the packet (dot side up) or else damage may occur.
• Do not pile the packets when reactivating.

Step 1. For best results, directly spread the packets in the microwave evenly (with no additional dishes or plates to hold them).

*Do not place the packet directly on the bottom of the microwave if the tray is removed.

Step 2. Reactivate according to the settings.

Shorter cycles are safer than overheating: Heat accumulates less evenly in microwaves. If unsure, reduce each heating cycle by 1-2 minutes. It is safer to repeat the process than to overheat in a single long session.

For 100g packets:

Microwave Output	Power Level	Amount	Time
700W	High/100% PL	100g x 1 pack	3+3 min
		100g x 2 packs	4+4 min
1000W	Mid-High/70% PL	100g x 1 pack	4+4 min
		100g x 2 packs	5+5 min

• Recharge in 2 times. Must let it cool before the second recharge.

For 200g packets:

Microwave Output	Power Level	Amount	Time
700W	High/100% PL	200g x 1 pack	4+4 min
1000W	Mid-High/70% PL	200g x 1 pack	5+5 min

• Recharge in 2 times. Must let it cool before the second recharge.

* For microwaves of different outputs, adjust the time accordingly.

* Reactivation is complete when the pink dot returns to blue or the packet returns close to its original dry weight.

Reactivate by Oven

Step 1. It’s recommended to place the packets on a wire rack. This ensures heat dissipates evenly from the bottom and prevents the printing ink from decomposing due to excessive contact heat.

*If you don’t have a wire rack, you can evenly spread the packets in an appropriate container (such as a shallow metal baking sheet) and put it in the oven.

Step 2. Heat at 150℃ / 300°F.

For 100g packets:

Amount	Temperature	Time
100g x 1 pack	150℃/300℉	30+30 min
100g x 2 packs	150℃/300℉	30+30 min
100g x 3 packs	150℃/300℉	35+35 min

• Recharge in 2 times. Must let it cool before the second recharge.

For 200g packets:

Amount	Temperature	Time
200g x 1 pack	150℃/300℉	30+30 min
200g x 2 packs	150℃/300℉	30+30 min

• Recharge in 2 times. Must let it cool before the second recharge.

Tips

• Do not reactivate unused new desiccant packets.
• Do not put in water as the desiccant will fail to work permanently.
• A packet will retain absorbed liquids internally to keep stored items dry and prevent damage from seepage.
• If the indicator dot’s color-indicating function is affected after multiple uses, weigh the packet to check its saturation level.

CAUTION

• Do not eat or inhale.
• Keep out of reach of children and pets.
• Packets will be hot after reactivation. Do not touch with bare hands.
• If a packet is broken, throw away.
• If swallowed, seek immediate medical attention.
