I having no luck trying to clean water marks off acrilic/clear plastic tank lid. ALL HELP WELCOME !.

[KittenFishMom]

Now let me first start by saying I dust a room by taking my eye glasses off and the dust disappears. I'm not "in to" cleaning, but I have a problem. I have an older tank lid with cut outs lined with clear plastic that have water marks on them. I want to use the lid, but am worried about the amount of light that will be blocked by this grime.

I tried the hose. I tryed straight white vinagar and rinsed with the hose. I tryed Fritz glass & acrylic cleaner. I'm wondering if baking soda might scratch the plastic/acryilic.  Anyone out that have any luck with this sort of stuff? I think the tank might have been salt water before I go it. I don't know if that latters.

All ideas very welcome!

@mynameisnobody Shouuld I put it on aftter wetting the plastic then let it sit or is it safe to scrub it before rinsing?

Wet surface, scrub, rinse, repeat for anything that didn’t come off on the first try.

Honestly I wouldn’t use any abrasive not specified for use on acrylic. Plastic is soft and micro abrasions can leave that unwanted “cut” look you see sometimes on cars in the sun.

 

An e-cloth or something of similar quality microfiber will be fine. Also it is 8 million times better on glass than windex or other glass cleaners. I despise the residue they leave behind.

 

if it still doesnt come out id go to tap plastics or amazon and order acrylic polish and buff. I like this stuff:
