Cleaning


Technilit:

offers a special detergent for tarpaulins.It is alcalin and is recommended for dirt typically encourtered on tarps.  

Price: 14€/l (TVAC)

Advices:   

It is advisable to wash the plastic sheet periodically to prevent encrustation of dirt and pollutants. 
Use a soft sponge and a cloth. Do not use abrasive sponges and avoid vigorous rubbing. Do not use a pressure washer. 
In any case, use of non-ionic detergents, with limited alcohol percentages. Do not use harsh detergents, acidic substances (descaling), alkaline detergents (strong degreaser), oxidizers, sodium hypochlorite (bleach) or hydrogen peroxide.  
If you have a grease stain on PVC fabric, it is possible to use occasionally and in small doses oil as diesel, gasoline or petroleum ether to remove the grease stain; rinse well after. 

Tricks


Take measurements:

Measure the width and the length of the exterior of your trailer with an accuracy of +/- 1mm. Then determine the desired height (usually between 15cm and 20cm) taking into account the position of the brackets or the rollers. A distance of 10cm to 20cm is required to stretch the elastic. Do not forget to take into account any fasteners for closing the tailboard. If you trailer has a fixed ladder rack (not removable), do not forget to indicate the size (width x length of the through parts) and their positions. Finally, indicate the desired position of the eyelets by considering the mode of attachment (peripheral or individual elastic). In case no hook or roulette can not be installed, if mudguards for double-axle trailers, the turnstiles will be provided.  

Hook or roulette:
This is a matter of personal appreciation. The wheels show no roughness and therefore does not risk injury to the operator. The hook ensures a more secure fit. The wheels allow a freer fixation. Conversely, the hooks must be more precisely set, any deviation from the vertical of the eye result in waves in the fabric.  

Elastic device or individual:
The trend is to prefer an elastic device for flat sheets and individual elastic for high tarpaulins. Note that in the latter case, the traction occurs only downwards, whereas with peripheral elastic, the tension on the sheet is more distributed and prevents waves in the fabric. Wave is less visible in the case of high tarpaulins thanks to its larger holding structure.  
 
How to install the brackets and rollers?  
Wheels : the wheels are set at about 10 to 15cm below the eyelets. They are positioned between the eyelets  
Hooks: The hooks are attached at about 15 cm from the eye. They are positioned in alignment with the eyelet. Ensure accurate plumb to prevent waves in the fabric.  

Avoid cow's rumen:
The flat sheets tend to accumulate rainwater. To avoid puddling, put some balloons (beach ball type) under the tarp. Adjust the height by  inflating more or less the balloons.   

Maintenance:    
It is recommended to periodically wash the cloth PVC in order to avoid the encrustation of dirt and pollutants.  
Use a soft sponge and a cloth. Do not use abrasive sponges and avoid vigorous rubbing. Do not use a pressure washer.  
In any case, use of non-ionic detergents, with limited alcohol percentages. Do not use harsh detergents, acidic substances, alkaline detergents, oxidizers, sodium hypochlorite or hydrogen peroxide.
