 Marine & Shipping Industry:
Removal of crude oil and other petroleum products from the holds of tankers: Safe-N-Clean should be sprayed into the holds by low volume, high pressure pumps, with the use of revolving spinner heads that can be lowered in to the hold. This type of operation suggests the use of a 5 degree Vee jet nozzle placed in the spinner heads. The process of spraying should commence as soon as possible after the ship is empty, to prevent the formation of volatile gases from the remaining crude oil or other petroleum residue. Continue the pumping process until Safe-N-Clean has covered the entire surface. For best results this solution should be allowed to set for about one hour, after which the Butterworth system should be used for 30 to 45 minutes. It is important to note at this point, that the Safe-N-Clean solution can be left on the interior of the holds for periods of time longer than one hour with no problems. The initial hour is recommended to give Safe-N-Clean time to break down the crude oil or like petroleum product, longer periods will not decrease its efficiency, since complete evaporation will not occur. Accordingly, the results will be the same if Butterworth spraying is delayed 24 hours, or if done in sequence. After this procedure is complete, the hold should be clean and gas free. If any gases do remain, then spray the interior of the hold with a mixture of 1 part Safe-N-Clean to 20 parts water through the revolving spinner heads. This will leave the tank gas free. Safe-N-Clean holds oil in solution and breaks it down to such a degree that it cannot stick back together. Once the reaction has occurred, the oil begins to lose its identity as an oil and takes on the characteristics of a water soluble. There is no reverse emulsion with Safe-N-Clean. |
| There are many more applications for Safe-N-Clean Industrial Cleaner Degreaser. When in doubt, try a test spot. On smooth surfaces, spray on and wipe off is usually sufficient. On grained or rough surfaces or where exceptionally difficult stains or soils are encountered, some agitation with an appropriate brush may be required. Where applicable, always wash from the bottom up and rinse from the top down. This will prevent streaking. |
