proved compound, and has for its objects to provide a paint remover adapted dt'or removing paint and varnish from automobiles, ships, all metal Work, and from wood work, to provide a comparatively inexpensive paint remover, to'provide a paint remover which will do its work rapidly and thoroughly Without detriment to the objects from which the paint is removed, and with? out discomfortto, the hands of the user.

Another object is to produce a paintremover which will do the work without the use of heat, and without the use ofj'a scratch brush or sand paper and the like. Marks treated with my improved paint because scratching is eliminated.

The product hereinafter described is particularly rapid in its action, free from detri mental ingredients, and, while having a cleansing action upon metals, is free from corrosive action in regard to the same.

The various compounds heretofore used for the purpose of removing paint have been found in some cases to be too strong, and in other cases, too wea When too strong, they soak in too much into wood and spoil the same, or they corrode the metal.

W'hen too Weak, they have only egression or spreading power, and the application must 40 be repeated a number of times to satisfactorily remove the paint or varnish. Others require the additional application of heat. I avoid these difficulties by providing a compound which will readily soak in and permeate the paint, and which will soften the same so that ,the use of a scratch brush is avoided. Aftir the application of my improved paint remover, the paint may be known as sodium hydroxide. are not left on the wood or metal work 1 Application 'filed August 18,1925. Serial No; 51,041.

leftfor a few minutes, and then rubbed off off with a wet cloth, or Washed off with a spray, of water from a hose.

To carry out my invention, I take say, 4 ounces of same in a pint of cold water having a tem perature of F., to make a strong starch solution. I then takeone-half pound of caustic soda and one-half pound of lye, and mix the same together. I then add one gallon of hot water of a temperature of 150 F., and again mix or agitate the same. I then add in the following order, two ounces of benzine', two and one-half ounces of ammonia, which has a strength of 7%, one ounce of commercial chloroform, and two ounces of lemon juice, and while adding these, I agitate the mixture by stirring the same. I then finally add the solution of corn starch, and again agitate the mixture, and it is then ready for use. The lye used, is ordinary lye, having the composition corn starch, and dissolve the Chemical compounds or similar substances having the properties of lemon juice, may be considered the equivalent thereof I am aware that the ingredients have separately and in other compositions appeared in soaps and detergent articles. Therefore, lay claim only to the combination and method of use given, and when united in the order specified.

I do not limit myself to the exact proportions given, which are taken as approximate, and may be varied in accordance with the nature of the material treated, or for the purpose required.

- lVhat is claimed is:

A paint remover formed by mixing together water, one and one-eighth gallons; caustic soda, one half pound;'lye, one-half pound; benzine, two ounces; ammonia (7% strength), two and one-half ounces; commercial chloroforn'l, one ounce; lemon juice, two ounces; corn starch, four ounces.
