It is built to last. But how long it lasts depends almost entirely on how it is maintained. A few hours of care per year can add years to the life of your product. Neglect, on the other hand, tends to compound. Small problems become structural ones when the fabric's protective properties are allowed to degrade.

This guide explains what Isacryl is, why it behaves the way it does, what damages it, and how to keep it performing the way it was designed to.

What Makes Isacryl Different

Understanding three properties helps explain every care instruction that follows.

Fiber-dyed color. Standard fabrics are surface-dyed: the color sits on the outside of the thread. Isacryl threads are dyed all the way through before the fabric is woven, which means UV exposure degrades the surface without reaching the color underneath. This is why Isabella products hold their color in high-sun environments where surface-dyed alternatives fade noticeably within a few seasons.

Full impregnation. Isacryl is not coated on the outside. It is impregnated throughout the material. Water beads on the surface and runs off rather than soaking in. This is a fundamentally different approach from spray-on waterproofing, and it is why Isacryl performs in sustained rain rather than just brief showers. It also means that the impregnation can be compromised from the inside as well as the outside, a distinction that matters for the care instructions below.

Breathability. Isacryl allows water vapor to pass through the fabric. This is intentional. A fully sealed fabric would trap humidity inside the awning or tent, leading to condensation on surfaces and a damp interior even without rain. Breathability manages the interior climate passively. It is part of why a well-ventilated Isabella setup stays comfortable overnight.

Why this matters for care

The impregnation that makes Isacryl waterproof is not permanent by default. It holds for years under normal conditions, but specific substances and behaviors degrade it. The care instructions below are not arbitrary. Each one protects the impregnation that protects you.

What Degrades Isacryl Over Time

The most common cause of Isacryl failure is not age or weather. It is the accumulation of substances that slowly break down the fabric's impregnation. Isabella's own testing at the factory has confirmed this consistently.

Salt air. Camping near the coast introduces salt carried on the wind. Salt binds moisture and holds it against the fabric surface, creating a sustained wet environment that degrades impregnation even in the absence of rain. If you camp regularly near the ocean, increase your cleaning frequency.

Aerosol propellants. Bug spray, sunscreen spray, hairspray, and deodorant are all harmful to Isacryl impregnation. The propellant gas, not just the product itself, breaks down the fabric's protective treatment. Apply these products away from the awning and allow them to settle before entering. This applies to the interior of the Camp-let tent as well.

Pollen, bird droppings, and insect residue. These are organic materials that, if left to sit, degrade impregnation through biological and chemical breakdown. They are easiest to remove when fresh. If you notice buildup during a trip, rinse the affected area with clean water rather than waiting until pack-up.

Air pollution and tree sap. Parking under trees or in areas with industrial air quality introduces particles that accumulate on fabric and slowly compromise waterproofing. Regular cleaning is the primary defense.

Household cleaning products. Standard dish soap, laundry detergent, and general-purpose cleaners strip the impregnation directly. Never use them on Isacryl. Even a single wash with household soap can noticeably reduce the fabric's water resistance.

Routine Cleaning

The baseline cleaning method for Isacryl is simple: clean water and a soft brush. No soap. Clean thoroughly at least twice per season, more frequently if you are in a coastal environment, camping under trees, or traveling in areas with high air pollution.

Three-step process:

• Wet the fabric thoroughly with clean water.

• Brush gently with a soft-bristle brush, working dirt loose while rinsing it away simultaneously.

• Finish with a thorough rinse to remove any loosened material.

For more stubborn dirt, including mold spots, bird droppings that have set, or heavy organic accumulation, use IsaClean, Isabella's purpose-formulated fabric cleaner. IsaClean is designed to clean Isacryl without stripping its impregnation. It is available through isabellacamping.com.

When to Re-Impregnate

Isacryl's impregnation is durable, but not indefinite. The clearest signal that it needs restoration is water behavior: when your fabric is performing correctly, water beads into droplets and runs off the surface. When impregnation is degraded, water spreads into a wet patch and soaks in rather than running off.

If you notice this, re-impregnation with AquaTex applied to the inside of the fabric is the fix, not replacement. Use AquaTex reproofing spray. Apply to clean, dry fabric according to the product instructions.

Prevention is simpler than restoration. Regular cleaning removes the substances that degrade impregnation before they can do structural damage. A well-maintained Isacryl product should not need re-impregnation frequently. Annual cleaning followed by a visual check of water behavior is sufficient for most customers in most conditions.

Storing Isacryl Correctly

How you store Isacryl between uses matters as much as how you clean it during use. The single most important rule: never pack Isacryl away wet.

Packing damp fabric creates the conditions for mold and mildew to establish themselves during storage. Once mold is present, removal is difficult and the impregnation in the affected area is likely compromised. If you have to pack up in rain, plan to re-open and air dry as soon as you return home.

Additional storage guidelines:

• Store in a dry location. A breathable bag is preferable to a sealed plastic container, which traps any residual moisture.

• Avoid prolonged compression. Extended storage in a tightly packed state creates fold stress in the fabric. If possible, loosen the packing for long-term storage.

• Keep window panels flat or loosely rolled, not sharply folded. If window panels have developed creases from storage, hang them near a heat source (not touching) for a day or two before use. This relaxes the film.

• Remove curtain holders before packing any reversible curtain systems. Leaving holders in place can damage window film during compression.

• Before first use of the season, inspect the fabric for any discoloration, mold spots, or areas where water no longer beads correctly. Address these before your first trip, not during it.

The Annual Maintenance Mindset

Isabella products are designed for ownership measured in decades, not seasons. The customers who get the longest life from their products are not necessarily the ones who camp the most carefully. They are the ones who spend a few hours each year on deliberate maintenance.

A reasonable annual rhythm looks like this: clean thoroughly at end of season, inspect impregnation, apply AquaTex to the inside of the fabric in any areas where water no longer beads correctly, check and lubricate zips, air dry fully before storage. That sequence, repeated yearly, is the difference between a product that lasts a decade and one that lasts twenty-five years.

Isabella products are built to earn that kind of care. The maintenance is not a burden. It is part of the ownership.
