英文名methylated spirit 是标签确认里面的句子，原话如下：
b) For markings required by 7.2, 7.4, 7.5 and 7.6, an additional test for durability is to be
performed. Markings are rubbed by hand, without undue pressure, first for 15 s with a cloth
rag soaked with distilled water, then for 15 s with a cloth rag soaked with methylated spirit
and then for 15 s with a cloth rag soaked with isopropyl alcohol.

没有找到卖这个的，而且加的话是以什么样的比例来，也是一个问题

英国药典标准
Industrial Methylated Spirits; IMS
   
Industrial Denatured Alcohol
   
DEFINITION
   
Industrial Methylated Spirit is a mixture of nineteen volumes of ethanol of an  appropriate strength with one volume of approved wood naphtha. Two strengths are  available containing 99% by volume and 95% by volume of alcohol (also known as 74  OP and 66 OP respectively).
   
CHARACTERISTICS
   
A colourless, clear, mobile, volatile liquid, boiling at about 78°.
   
IDENTIFICATION
   
Mix 0.1 mL with 0.05 mL of an 11% w/w solution of orthophosphoric acid  and 0.25  mL of dilute potassium permanganate solution. After 1 minute add a few mg of  sodium metabisulfite and shake until the mixture is decolorised. Add 1.5 mL of a  50% v/v solution of sulfuric acid  and a few mg of finely powdered chromotropic acid  sodium salt, shake well and heat on a water bath for 5 minutes. A deep violet colour  is produced.
   
TESTS
   
Acidity or alkalinity
   
25 mL requires not more than 0.2 mL of 0.1M sodium hydroxide VS to produce a pink  colour with phenolphthalein solution R1 and not more than 1.0 mL of 0.1M  hydrochloric acid VS to produce a red colour with methyl red solution.
   
Clarity of solution
   
Dilute 5.0 mL to 100 mL with water. The solution is clear, Appendix IV A.
   
Apparent density
   
For '66 OP' grade, not greater than 811.6 kg m-3, and for '74 OP' grade, not greater  than 792.8 kg m-3, Appendix V G.
   
Aldehydes
   
To 5.0 mL add 5 mL of water and 1 mL of decolorised fuchsin solution and allow to  stand for 30 minutes. Any colour produced is not more intense than that obtained by  treating in the same manner 5 mL of a 0.005% w/v solution of redistilled  acetaldehyde in aldehyde-free ethanol (96%) (50 ppm).
   
Non-volatile matter
   
When evaporated and dried at 105°, leaves not more than 0.01% w/v of residue.

大概就是工业酒精吧
