Jomboy Mediaマグのケア：プリントの色あせを防ぐ方法

Quick answer

Wash your Jomboy Media mug by hand with warm water and mild dish soap whenever you can. If you use a dishwasher, keep it on the top rack, choose a low-heat or air-dry cycle, and avoid abrasive sponges or harsh detergents. Those three habits prevent most print fading and cracking.

A printed mug lives a hard life: hot coffee, repeated washing, and the occasional microwave reheat. The design on your Jomboy Media mug is printed onto the surface, so the way you clean it decides how long the colors stay bright. Most fading is not random — it comes from heat, abrasion, and strong chemicals.

This guide walks through the exact steps for washing a printed mug, plus the mistakes that quietly wear down the print over months. You do not need special equipment. A few small changes to your routine are enough to keep the design looking new.

Why mug prints fade

Printed mug designs sit on or just below a coated surface. Heat expands and contracts that coating, and detergent chemicals slowly break it down. Abrasion from scrubbers and stacked dishes scratches the print directly. Over time these forces combine, and colors look chalky or start flaking at the edges.

The biggest single factor is the dishwasher. High heat during the wash and especially the drying cycle is harder on prints than most people expect. Hand washing removes almost all of that stress, which is why it is the default recommendation for any mug you want to keep looking sharp.

• Heat, abrasion, and harsh detergent are the three main causes of print fading.
• The dishwasher drying cycle is often hotter than the wash cycle.

How to wash a printed mug by hand

Fill the mug with warm — not boiling — water and add a drop of mild dish soap. Wipe the inside and outside with a soft sponge or cloth. Pay attention to the rim and the area around the print, but do not scrub the design itself with anything textured. Rinse thoroughly and dry with a soft towel.

Avoid steel wool, scouring pads, and gritty cleansers. They may not remove the print in one wash, but they dull the surface and make future fading more likely. If you have a stubborn coffee stain inside, a paste of baking soda and water left for a few minutes works without touching the print.

• Use warm water and mild soap, not boiling water.
• Dry immediately with a soft towel to avoid water spots on the print.

If you must use a dishwasher

Sometimes hand washing is not realistic. If your mug goes in the dishwasher, place it on the top rack and away from the heating element. Choose a gentle or light cycle and turn off heated drying if your machine allows it. Let the mug air dry or hand dry it afterward.

Do not run a dishwasher cycle with the mug still hot from the previous load, and do not pack it tightly against other dishes. Contact with other items during the cycle causes scratching. If the print already looks dull, switch to hand washing from that point on to slow further damage.

• Top rack only, away from the heating element.
• Skip heated dry — that is the hottest part of the cycle.
• Do not overload; contact with other dishes scratches the print.

Microwave, soak, and storage habits

Do not microwave a printed mug unless the product information specifically says it is microwave safe. Microwaving heats the mug unevenly and can weaken the print coating. It also risks scalding if the mug has a metallic finish or trim.

Skip long soaks in soapy water. Overnight soaking gives detergent more time to work on the print surface. Store mugs so they are not stacked rim-to-print or rattling against each other in a crowded cabinet. A little felt pad or a folded paper towel between stacked mugs prevents scratches.

• No microwave unless the mug is labeled microwave safe.
• Avoid overnight soaking in soapy water.
• Store without stacking mugs directly on top of the print.

Step-by-step mug care routine

1. Step 1: Rinse right after use: Give the mug a quick warm-water rinse before coffee or tea residue dries. Dried residue tempts you to scrub harder, which is what actually damages the print. Checkpoint: if you need to scrub, you waited too long.
2. Step 2: Wash with mild soap and a soft sponge: Use warm water, a drop of mild dish soap, and a soft sponge or cloth. Wipe the print gently rather than scrubbing it. Checkpoint: no steel wool, scouring pads, or gritty cleansers.
3. Step 3: Rinse and dry immediately: Rinse all soap off, then dry with a soft towel. Air drying is fine, but towel drying avoids water spots and mineral buildup on the print. Checkpoint: the mug should be dry before it goes back in the cabinet.
4. Step 4: Choose dishwasher settings carefully: If using a dishwasher, place the mug on the top rack, away from the heating element, on a gentle cycle with heated drying off. Checkpoint: if the mug comes out too hot to touch, the cycle was too hot for the print.
5. Step 5: Store without stacking on the print: Keep mugs from rattling against each other. Add a soft barrier between stacked mugs if cabinet space is tight. Checkpoint: no direct contact between a mug base and another mug's print.

Jomboy Media products worth protecting

• baseball-culture-comfort-colors-vintage-tee-f20330b92e634e8249bdead8-2075242">That Atlanta Culture: Printed in the USA with fade-resistant inks on a premium Comfort Colors shirt. Fade-resistant inks help the design hold up, but the same heat and abrasion rules apply — wash it inside out and skip high heat.
• BRYCE HARPER CHOS3N ONE: Printed in the USA with fade-resistant inks on a premium 50/50 blend sweatshirt. The 50/50 blend is a good candidate for low-heat drying; high heat is the fastest way to shrink the fabric and dull the print.

A Jomboy Media mug does not need special products or a complicated routine. Hand wash it when you can, keep the dishwasher on its gentlest setting when you cannot, and avoid stacking mugs on the print. Those habits are enough to keep the design looking sharp for years.
