Cleaning in a two-tank machine
With the new technology in chemistry and the development of a detergent conditioner like Royaltone Detergent Plus that stabilizes the colors and retains the softness of suedes and leathers, it is now possible to dryclean suedes, leathers, furs and fabric combinations in any two-tank drycleaning machine in any drycleaning fluid, including perc, petroleum and Exxon 2000.

If the two-tank machine has only one operating tank and the second tank is only able to store drycleaning fluid to be pumped over to the operating tank when needed, it is essentially a one-tank machine. The variations possible in its use for cleaning suedes, leathers, furs and cloth combinations are the same as described last month for a one tank machine.
If the two-tank machine has two operating tanks that can be operated independently of one another as two separate systems and do not share the same drycleaning fluid, then there are also three variations by which it can be used to clean suede, leather, fur and cloth combination items.
First variation
The first variation is also the easiest because it is the least demanding of the machine operator and most flexible while providing the highest quality results.
In this variation, the drycleaning fluid in the entire system of the first of the two operating tanks is charged with a six percent concentration of the detergent plus conditioner.
This six percent tank system is then used to dryclean all dark and bright colored suedes, leathers, heavy textured furs and cloth combinations in the same way that cloth items are cleaned without color loss, fading, stiffening or drying out of the skins.
The drycleaning fluid in the entire system of the second of the two operating tanks is charged with a two percent concentration of the detergent plus conditioner.
This two percent tank system is then used to dryclean all light and pastel colored suedes and leathers, light textured furs (rabbit fur) and cloth combinations in the same way that cloth items are cleaned without color loss, stiffening or drying out the skins.
This same two percent tank system can also be used for drycleaning regular cloth items with excellent drycleaning results, without fading and bleeding, without streaks and swales on silks, without blotches in down filled items (which are commonly experienced in drycleaning) and with much less wrinkling in the drying cycle, easier pressing and longer filter life as extra benefits!
Second variation
The second variation to the way that a two-tank drycleaning machine can be used to clean suedes, leathers, furs and fabric combinations is more demanding of the machine operator and less flexible.
In this second variation, the drycleaning fluid in the entire system of the first of the two operating tanks is charged as before, with a six percent concentration of the detergent plus conditioner.
This six percent tank system is then used to dryclean all dark and bright colored suedes and leathers, heavy textured furs and cloth combinations.
In addition, this six percent tank system is also used to dryclean all light and pastel colored suedes, leathers, light textured furs and cloth combinations.
The drycleaning fluid in the second of the two operating tank systems is charged with a one percent concentration of the detergent plus conditioner and is used strictly for drycleaning only cloth articles with excellent results, including far less bleeding, fading, streaking, swaling, blotches, wrinkles and with easier pressing and longer filter life!
Third variation
The third variation to the way that a two-tank drycleaning machine can be used to dryclean suedes, leathers, furs and cloth combination is the most demanding of the machine operator and is the least flexible of the three.
In this third variation, the drycleaning fluid in the entire system of the first operating tank is charged with a two percent concentration of the detergent plus conditioner. This two percent tank system is then used to clean all light and pastel colored suedes, leathers, light textured furs and cloth.
This same two percent tank system will be used to supply drycleaning fluid to the wheel where its charge will be raised to six percent by the addition of more of the detergent plus conditioner for batch cleaning the dark and bright colored suedes, leathers, heavy textured furs and cloth combinations by the batch method, as described previously.
In this third variation, the drycleaning fluid in the second operating tank system is charged with one percent concentration of the detergent plus conditioner as in the second variation and it is used strictly for cleaning cloth items with the same carry-over benefits of good drycleaning with much less color loss, bleeding, fading, streaking, swaling, blotches, wrinkles and much easier pressing, longer filter life and no odor. Leather and cloth trimmed with suede or leather may not give the same results if used as described in this article.
