RXSOL-20-T-300-210 has a long non-polar hydrocarbon chain and a highly polar group at the end of the molecule thus having a cleaning power better than ordinary soap.
CHARATERISTIC: ( Why RXSOL-20-T-300-210, is better than soap?)

1) The %u201CT-Pol Heavy Duty%u201D are superior to soaps  because  they donot form  insoluble salts Ca+²,Mg+², & Fe+³,ions as soaps do. For e.g :- 2RCOO¯Na+  +Mgso4  Ù(RCOO)2 Mg+²  + Na2So4 Soaps    Insoluble 2R  So3¯Na+  + MgSo4[ R  So3¯]2Mg+² +Na2So4  T-Pol Heavy Duty.

It also helps to detect pinholes after welding.
Why Passivation required ?
1. Stainless Steel owes  its corrosion resistance to the formation of a chromium oxide surface layer but this happened due to presence of oxygen , And if the oxide has been stripped, perhaps by pickling, then the oxide layer takes a short time to reach its full thickness and this can be accelerated by passivation.
2. The heat tint produced by welding is not only unsightly but the thicker oxide layer includes chromium…..
