its close. its not actually that hard to make, if you dont mind the chance of blowing yourself up.
the pseudoephedrine is the easy one to get, however, to make real crystal meth, you need Iodine. which isnt extractable from anything really, and you are flagged like hell if you ever buy any.
i am not sure why you would need windshield washer fluid, other than for methanol, which is just used to extract the pseudoephedrine from the Sudafed.
and the drano i would think is for lye, which i think is just to crystalize the ingredients.
however, without Iodine, phosphorus and one other ingredient, all you have is with those 3 tools, is super pure sudafed.
which will still keep you zingin for quite a while!
