How to Remove Ink Stains from a Nylon Bag — When a pen dries on the peach-colored lining, don’t wash it—instead, carefully remove the stain fiber by fiber

CASE STUDY | SPECIALTY TEXTILE STAIN TREATMENT

A Dowa bag made of nylon with dried-on pen ink stains requires a different approach than washing a regular bag. Ink stains left for too long can become more difficult to remove, especially when the ink pigments have interacted with the fibers and the surface structure of the material.

In this case study, SHELLA uses BeZerO Ink Remover as part of its in-house professional ink stain removal system. The focus is not merely on making the surface appear clean, but on evaluating the condition of the material, color stability, and how the stain responds to the treatment.

To remove dried ink stains from nylon materials like this Dowa bag, you’ll need BeZerO Ink Remover + an absorbent white cloth + a soft brush suitable for nylon surfaces—not plain water or wet wipes.

Ink stains aren’t always the same. Ballpoint ink, gel ink, permanent marker ink, and pigment-based ink may require different treatment approaches. Therefore, don’t immediately rub the stain or pour household cleaning solutions onto the surface of the bag.

WHY – Why Is BeZerO Ink Remover More Effective Than Alcohol or IPA?

You should use BeZerO Ink Remover as a professional treatment rather than trying alcohol or IPA on your own, because the characteristics of the ink and the stability of the nylon dyes vary, and alcohol can affect certain dyes or surface layers, causing color changes that are difficult to correct.

BeZerO is SHELLA’s in-house ink stain treatment system. This product is used as part of a stain treatment procedure that takes into account the type of ink, the fabric’s composition, the age of the stain, color stability, and the history of previous treatments.

Alcohol or isopropyl alcohol (IPA) is not a universal solution for ink. Using it without testing may pose a risk of discoloration, dye migration, or changes in appearance on certain materials. The results cannot be guaranteed based solely on the fact that the material is nylon.

WHERE – Where Can I Get Ink Stain Removal for Dowa Bags in Surabaya?

If you’re in Surabaya, don’t just take your ink-stained clothes to a pay-by-weight laundry—take them to SHELLA Premium Laundry & Dry Clean Surabaya at Jl. Nginden VI B No. 1B, Sukolilo, which offers inspection services and specialty stain treatment for textiles and items requiring special care.

WHO – Who Performs the Dowa Bag Treatment?

This process is carried out by SHELLA’s team of technicians, who follow internal procedures for inspecting materials and treating ink stains—not simply washing the bags like a regular laundry service—so that every treatment decision is based on the condition of the material, color stability, and the results of evaluations conducted before and after the process.

Removing ink stains requires more than just laundry skills. Technicians need to identify the type of stain, understand the characteristics of the fabric, conduct compatibility tests, and determine whether the treatment can proceed.

For Dowa nylon bags, some aspects to check include:

  • The type and characteristics of the ink that has adhered.
  • The age of the stain and how dry it is.
  • Color stability of nylon.
  • The presence of additional coatings, linings, or finishes.
  • Traces of a previous cleanup attempt.

WHEN – When Should You Bring a Dowa Bag with Ink Stains?

Dried ink stains on Dowa bags should be brought in for inspection as soon as possible, because the longer the stain remains on the material, the greater the likelihood that the ink will interact with the fibers or the finish, making it more difficult to treat and requiring a more complex treatment process.

Don’t wait until the stain spreads further or try different chemicals one after another. Previous treatments can alter the nature of the stain and affect how the material responds to subsequent processes.

Avoid the following three things:

  • Do not scrub the stain with a tissue or a rough brush.
  • Do not mix alcohol, bleach, and other cleaning solutions.
  • Do not use direct heat or a steamer without first evaluating the material.
Urgency: The sooner the bag is inspected, the more opportunity there is to evaluate treatment options before the stain undergoes further changes. There is no universal time limit that guarantees the ink can be removed.

Don't Let Ink Stains Ruin the Look of Your Dowa Bag

Please send photos of the stain, the bag’s overall condition, and details about when the stain occurred to the SHELLA team for an initial assessment.
