I screwed up, I meant to say, you can put a cap full in your tank, it will grab onto water and burn it off, good for cleaning your brakes, and washer wiper fluid just a cap full though

So that I'm clear, you're saying add a capful of isopropyl alcohol to my EMPTY master brake reservoir, shake it around, pour it out, let it dry, then fill with DOT 4?

You was saying you took the reservoir out? that's what I was talking about

yea its ok it will dissipate and should leave it clean, it burns off

it will take out any residue left in the reservoir and wont leave any itself

Thank you for reassuring me. Attached is the cleaned reservoir. I will pry it off and rinse with the alcohol and let you k ow how it goes.

I have never used Simple Green (is that an american product? dont know what residues it leaves behind

I when I purchased the used unit I googled how to clean and found a UK owner that said to soak with "Clean Green." Couldn't find that in the U S. Simple Green is an environmentally-green biodegradable all purpose cleaner/degreaser that doesn't suppose to leave a residue

if you trust the stuff leave as is then

Well it did leave a light residue on the wall of the main chamber but I got it off. However, the smaller separate chamber that you can't access still has a light stain towards the top right-side but I thinks that the old fluid. I just didn't know whether rinse again or leave it alone. Isopropyl alcohol dries fast so that may be worth a try.

The thing is plastic will yellow, the only way I know of to get it white again is to leave it in the sun and it whitens up again (but I dont know why that works but it will)

Entering winter now not many sunny days. Yesterday would've worked. Lol
Had a snow storm last week.

All I need is a capful? Remember the tank is empty. Since the reservoir is divided into 2 or 3 separate chambers, not sure if I can get a capful on the other side of the reservoir. Can I pour maybe 1/2 a cup?

I always used methalated spirit to clean brake cylinders,it evaporates quickly after its done its job.

I will Google that
Thanks

I think the americans call is denatured alcohol? it works the same its not oil based

Got it! I'll get some today, pour it in reservoir, swish it around and let it dry.

Readily available in chemists (pharmacies) in the UK and hardware stores.

An airline helps with the drying.
