How to Wash Out Common Lab Chemicals

    Water Soluble Solutions
    (e.g., sodium chloride or sucrose solutions) Rinse 3-4 times with deionized water then put the glassware away.

     
    Water Insoluble Solutions
    (e.g., solutions in hexane or chloroform) Rinse 2-3 times with ethanol or acetone, rinse 3-4 times with deionized water, then put the glassware away. In some situations other solvents need to be used for the initial rinse.

     
    Strong Acids
    (e.g., concentrated HCl or H2SO4) Under the fume hood, carefully rinse the glassware with copious volumes of tap water. Rinse 3-4 times with deionized water, then put the glassware away.

     
    Strong Bases
    (e.g., 6M NaOH or concentrated NH4OH) Under the fume hood, carefully rinse the glassware with copious volumes of tap water. Rinse 3-4 times with deionized water, then put the glassware away.

     
    Weak Acids
    (e.g., acetic acid solutions or dilutions of strong acids such as 0.1M or 1M HCl or H2SO4) Rinse 3-4 times with deionized water before putting the glassware away.

     
    Weak Bases
    (e.g., 0.1M and 1M NaOH and NH4OH) Rinse thoroughly with tap water to remove the base, then rinse 3-4 times with deionized water before putting the glassware away.

this thread should be in 'set the style'

unless youre talking about glassware.

abrasive solution

mix up a saturated solution of distilled water and table salt or rock salt

pour solution in your glassware and swirl/shake, this should scrape off any crap caked onto your glassware and as long as you're only shaking or swirling you won't damage your glass

dump out solution, repeat until clean

rinse with distilled water until all the salt is gone

let dry

For really tenacious stains you can throw the glassware in an annealing oven at under 800C and let it cool slowly. Those temps will bake just about everything off the glass and make it look brand new.

Another good substance for cleaning glassware is Peroxymonosulfuric acid, also knows as Caro's acid (just take a look at Wikipedia)

Fairy liquid has always been surprisingly good. I shit you not.
