One of your worst nightmares…accidentally filling the water tank with fuel – bad enough if it is your own motorhome, scary if it’s a rental.

But don’t beat yourself up! It happens to people more often than you’d imagine. Luckily all is not lost and before you think about replacing the water tank there’s a very good chance that you can solve the problem quite easily.

We’ve had a number of customers who have faced this predicament. With a little bit of effort, following a simple procedure, you can fix the problem.

We’ve had excellent results with Simple Green Crystal. Crystal is a highly effective, concentrated, all-purpose degreaser and cleaner formulated for critical cleaning applications that demand a fragrance-free solution. Crystal contains a blend of highly effective surfactants that are activated by cold or warm water and is an ideal and effective degreaser/cleaner for such situations. Specially developed for the food and health industries, Crystal is NSF labelled A1, A2, A4, A8, B1 and C1 for use in food processing and handling facilities.

What To Do If You’ve Put Diesel In The Water Tank

First flush the motorhome’s water tank out several times and then start as follows:

Step One

Mix 4L of Simple Green Crystal with the contents of the tank i.e. 4 L to 46 L water roughly a 1:10 dilution  (note if you can use warm water that’s better - no need to go over 40 degrees C)

Leave for a couple of hours at least then flush out

Step Two

Flush through the whole system with water

Step Three

Mix 2L of Simple Green with the content of the tank

Leave it in for an hour then flush out

Step 4

Flush the whole system with water

Step 5

Mix the 1 Litre of Simple Green with the content of the tank

Leave for 30 minutes then flush out

Step 6

Flush the tank out with water

This should have done the trick but if not then depending on how bad it is then either do another 1L or go to 0.5L and continue.

And…to avoid using too much, check after each flush out of water and between the steps, to see if it has already worked.
