Unfortunately I’ve only just been informed of this issue, and I would like to discuss it with you so that we can resolve it.
I’ve noticed for some time now that we have been receiving very high cleaning prices, and this misunderstanding may be the reason.
The cleaning price which we need you to quote, is the price for cleaning the product based on the assumption that each tank is returned with reasonable residue. Below you mention an upper limit for residue of 50 kilos, but the weight will obviously vary dependent on the specific gravity of the product. Do you mean 50 litres of residue is your limit please?
