I have a rough, synthetic, foam-backed covering stuck to a bulkhead and the hull in an aft cabin that has always had mildew stains and oil spots. What would be the best way to clean it in situ?
By clean do you mean remove it or get rid of the stains?
If you mean remove the mildew etc, then the best way would probably be to use a mildew cleaner designed for bathrooms (testing for colour fastness first, and or a small steam cleaner. (the steam alone should kill the mildew spores).
We had some forming on the inside of the hull lining a few weeks ago. Attacked it with Starbrite Mildew Remover - It didn't appear to be immediately effective, but it's gone now. However, when they say test it on a small area first they really mean it. It was fine on our carpet lining and seat cushions, but it beached a bed sheet within a few seconds
Get rid of the stains... as it covers quite a large area to varying degrees I need something that can easily be applied and removed. I thought about spraying with bleach, leaving it for a while and then spraying again with fresh water to rinse it and then use a wet vacuum cleaner to remove the excess. Maybe steam cleaning would work...
Most mould/mildew cleaners are basically only bleach, so using a simple bleach solution would be more cost-effective. However, you'd probably get better results with a cleaning product containing disodium octaborate, which is a powerful fungicide. This should be shown in the ingredients list on the label.
When will people appreciate that Milton is basically just a weak solution of bleach - with a very expensive price tag. OK, it has been modified slightly (mainly by adding salt), but it's still basically bleach. If you prefer to use it in a water tank, that's perhaps understandable, but using it for general cleaning is like tearing up £10 notes (oh, but that's what boating's about, isn't it?)
Which is why I recommended the cheap Sainsbury's version.
At least it is mixed to the correct 'weakness', which I suspect is less hazardous than trying ot diilute a bottle of full strength Domestos. /forums/images/graemlins/smirk.gif
My new username, formerly crisser, was a result of a drunken night with a load of boaties on Saturday. Not due to a real catastrophe, but a close shave in the infamous Swellies when a big MOBO insisted on entering from the East and trying to squeeze me between himself and Prices point.
Add 50ml of ordinary cheap household bleach to about 2 litres of warm water. Add a squirt of washing-up liquid. Mix. Wear rubber gloves and protective goggles. Cover any upholstery, woodwork, etc with polythene sheeting. Using a thin sponge, rub the bleach solution on to the soiled area. If the texture of the covering is very rough, you might use a nailbrush to work into the texture. Leave for a couple of hours. Wipe down with a sponge and warm water. Allow to dry. Repeat if required.
Oil spots can often be removed with mild solvents such as white spirit, meths, nail varnish remover, etc, but test on a hidden part first because solvents can sometimes cause synthetic materials to go sticky.
We had mildew on our beige coloured curtains. Bleach would have marked this fabric so I used isopropyl alcohol as recommended by a website. Maplins sell this in a spray can and it is marketed as ‘Servisol IPA 170’.
I sprayed it on and let it dry. It killed the mildew and reduced the staining quite a bit to light grey fleckles rather than black ones. You have to look hard to see them. It did not mark the fabric in anyway.
