Caution! Use only a clean tent brush and no cloths or other materials. Cloths have an abrasive effect, which can damage the tent fabric. Additionally, cloths may contain soap residues that can impair the waterproofing.

Bird Poo and Mud

• Let the stain dry completely.
• Scrape it off the fabric once dry.
• If a mark remains, gently wipe it away with a clean tent brush and lukewarm water (don’t scrub hard!).
• No further action needed—the sun and a rain shower will fade any lingering marks naturally.

Grease Stains

Prevention is better than cure with grease, but if it happens:

• Dab (don’t rub!) the stain with kitchen roll to absorb the grease.
• For heavy or leaking stains, use a specialist tent cleaner, but note it may affect the waterproofing.
• Re-impregnate the treated area afterwards to restore protection.

Mould and Algae

Mould and weather stains are best prevented, as they can permanently damage the fabric.

• Watch for grey-black streaks or black specks.
• Brush them off with lukewarm water if caught early.
• If mould has set in, it’s often too late. For older tents, consider replacing it and maintaining the new one carefully.
• For newer tents, try cleaning with a mild chlorine solution (1:10 chlorine-to-water ratio). If that fails, use a specialist tent fabric cleaner.
• After cleaning, re-impregnate only the treated areas to prevent leaks and new mould growth.

Dust (and Rain Streaks)

On dusty campsites where cars kick up clouds, grab a (dedicated) carpet beater and give your tent a gentle tap daily to shake off dust.

• Skipping this risks vertical rain streaks when the first big shower hits.
• Streaks are tough to remove as they sink deep into the cotton fibres. Sun and several rainfalls will gradually fade them.
• For instant removal, use a tent cleaner, but re-impregnate the area afterwards.

Tree Sap

• Wet sap: Carefully scrape it off with a spoon.
• Hardened sap: Leave it alone—it’ll crumble off naturally over time. Don’t scrape it, as this damages the cotton fibres.
• If packing a tent with wet sap, place cardboard between the fabric to prevent sticking.

Candle Wax

• Let the wax harden fully—don’t try to remove it when soft.
• Once hard, break or gently scrape it off. Use a spoon, not a knife, to avoid damaging the tent.

Drink Stains

Drink stains are usually easy to tackle:

• Red wine: Sprinkle salt over the stain, let it soak in, dab with kitchen roll, and rinse with lukewarm water.
• Coffee: Use lukewarm water and a clean tent brush.
• Act quickly to prevent permanent discolouration.
