Gently use pure acetone (no perfume or dye) on a q-tip. just dampen the q-tip and only use one stroke per q-tip do not use any pressure as this will damage the mirror surface Use distilled water to rinse mirror. LET AIR DRY!

I have some spots of superglue on a lovely shirt, is there a substance which will remove it?


Probably not without damaging the fabric because these glues are so hard. 2 products I would try if you can get them where you are:
1. tea tree oil
2. Eucalyptus oil.

These will react with normal glues and break them down without harming the fabric or taking out any colour. I have not tried either of them with any of the super glues so I cannot say if it will be successful with such super tough products. I would also test them on another piece of similar fabric spotted with the glue before using them and that will tell you if they will work on the SG.

Other than that you would need to try various strong solvents to see if they would break down the glue and enable you to remove it. The problem is you may end up with a stain, loss of colour or some damage to the fabric if it is a sensitive fabric. If you test some of these on an old piece of similar fabric you have spotted with the glue you will be able to see which one worked without harming the fabric.

If you can buy a bottle of dry cleaning fluid (I cannot remember the technical name) you may be able to move it using a liberal amount of that product or just soaking the areas with the spots in the fluid. Be careful handling it as it is pretty toxic.

Applying steam (from a boiling kettle ) to areas of the fabric affected may soften the glue a little and enable you to roll it off the fabric if it is not heavily impregnated. Whilst this can work with some of the softer glues it may not with the SG. I would also test it first on another piece of fabric

Dropped a glob of Gorilla Glue on laminate flooring. Dried. Haven't tried to remove it yet.


The "normal" response would be to use acetone which is a solvent for gorilla glue (or super glue), but acetone will dissolve the material used to laminate the floor and cause it to become cloudy. I've had success scraping globs of glue off with a fingernail. Better yet, try putting an ice cube over the spot of glue until it gets brittle, and you should be able to scrape it off. Hope this works! Good luck!

Audi a3 black edition head liner has a small cigarette burn


Youre going to need a razor blade and some super glue. Take the razor blade and SCRAPE some fuzz from an inconspicuous spot of the headliner(maybe under a trim piece or light bezel) apply a small amount of glue to the burn, Then after you apply the glue, take the fuzz that you accumulated and apply to the glue. Lightly.

When viewing venus or other stars there a black spot in the center of the object. It appears to be the 2nd mirror refleting to the main miror. what have I done incorrect?


You are NOT in focus. Turn the focus knob a little until you see a perfect "disk" for the planet. Stars are always POINTS of light, with a telescope or without a telescope.

The seal of the dishwasher is broken and the spot welding on the stainless steel strip that holds the seal has pulled away from the tub.


use super glue to glue in place in spots cut away seal near the weld seams, then make sure the door closes ok then get 5 minute epoxy and glue the seal on where it comes off, it's a permanent fix for a old machine but it will work. so go ahead and replace the seal.
