Done in 3 steps
Step 1
Clean your tent using Ultramar’s Sprayhood & Tent Shampoo
The Sprayhood & Tent Shampoo removes most normal dirt from your polyester or cotton tent.
● First of all, clean the tent canvas with lukewarm water and a soft brush. This will already remove some of the dirt.
● Apply Ultramar Sprayhood & Tent Shampoo to the wet tent and brush off the dirt thoroughly. You could use a plant sprayer and a firm, soft brush to do this.
● Leave the shampoo to soak in for approximately 20 minutes.
● Remove the shampoo and dirt using the brush and plenty of water.
● Rinse well.
● Allow the tent canvas to dry completely before impregnating or storing it.
Step 2
For tough dirt, use Ultramar’s Power Cleaner
The Power Cleaner removes ingrained and stubborn stains for cotton and polyester.
● Apply Ultramar's Power Cleaner to the dry tent canvas. Use a spray, plant sprayer or soft brush to apply. Rub in well.
● Leave to soak in for approximately 1 hour. Don't notice any change? Apply additional Power Cleaner and brush in again. Leave to soak in again. Repeat this as many times as required until the stains have disappeared.
● Remove the cleaning agent and dirt using the brush and plenty of water.
● Rinse well.
● Allow the tent canvas to dry completely before impregnating or storing it.
Step 3
Polyester tent: impregnate using Sprayhood & Tent Protector
The Sprayhood & Tent Protector impregnates the canvas, keeping the tent waterproof and repelling dirt.
● Make sure that the tent is clean and dry.
● Apply Ultramar's Sprayhood & Tent Protector generously and evenly. Make sure that the canvas is completely saturated. You could use a spray or plant sprayer, for example.
● Also treat the inside of the tent, where weather stains and mould can easily accumulate.
● Remove the impregnation agent from the plastic windows straight away if your tent has them. You could use a damp cloth to do this.
● Allow the tent canvas to dry thoroughly.
● Repeat the treatment if required, for example on the tent seams.
