I have a kitchen worktop with what was good quality laminate 10-12 years ago
(can't recall the 'make' now).
The problem is that some of the surface has gone 'sticky' - and yes it does
get wiped clean.
It's only in patches - mainly around thehob area (gas).
The surface is still hard and has not discoloured or chipped at all, its
just that it feels sticky and not the normal smooth 'polished' finish which
there is elsewhere.
Any ideas why this should have happened, and is there anything I can do to
get it back to good condition. It would be a nightmare of a job to have to
replace the worktop now.
Try a leetle bit of Mr Muscle oven cleaner on it.
After trying it on a hidden bit first.
Fat vapour condenses and eventually dries out to a sort of linseed oil
like rubbery muck around hobs. Strong alkali will shift it, but *may*
attack the laminate, so get it on, leave a few minutes and get it off.
It may affect the glue its put on with tho. Depending.
No, but it can chemically alter the top layer. Most lamniates don't have
surface colour - there is a substrate of smething like phenolic resin
and paper, then a color layers, and on top a clear layer of abrasion
All of which are _resonably_ solvent and dirt proof, and definitely
HOWEVER I used to have a Formica laminated top on a workbench years
ahgo. Cellulose thinners actually softened the top layer, and allowed me
to wipe it, and the pigment underneath, off.
Or was it? Might have been nitromethane that did that...
Anyway, hydrocarbon solvents and strong alkali will both lift heavy fat.
The trouble with hydrocarbons is that they don't change what is there -
just dissolve it, and when they evaporate, its still there.
The key to dgreasing with solvents os to splp them on then use a
detergent to make the whole shebang water-soluble. But alkali turns the
fats into detergents anyway, more or less.
The trick is to use just enough to attack the grease, not anything
else.Many plastics ARE chemically altered by alkali. Many are not. Only
way is to test and try.
BTW acids like vinegar to bugger all to grease. They are useful tho to
neutralise alkaline residues after you have used the caustic :-)
Mr Muscle oven cleaner is powerful Mooti. It appears to be spray on
caustic foam. I use it on all my vitreous enamel pans when burned on fat
builds up, and the aga top. You need a good extracor fan as well tho.
Cumulative build up of polymerised fats/oils?
My first plan of attack would be a strongish solution made up with washing
50p a bag in supermarkets.
An unbelievably effective cleaning product.
