What is your budget for giving money to your parents? If you move in with BF, does that change as you are now having different expenses and perhaps saving towards other goals?

Your budget should reflect how much you have/put in the shared account. Nothing else should be in it, only what you give to your parents as gifts (or shared bills). It should also be an amount that do not take away from your other goals - be it food, furniture, rent, clothes, hobbies, retirement, travel, car, haircuts (and on and on the list goes). I would not be surprised if BF refuse to have merged financial situation with you until you've set an amount that does not mean he too supports your parents to the detriment of his own goals. He shouldnt. You shouldnt.

If you want to help, help. But do so with open eyes and in a way that does not hurt your own financial situation or your BF's.

First, soap and lukewarm water, scrub the stain. Lift up the stain by patting it dry with a clean rag. Or, use a carpet cleaner. Use vinegar in the rinse-water if your carpet wont stain from that - it will help neutralize the urine/ammonia/soap. Again, lift up using clean rags (or a carpet cleaner).

Bile soap or lemon soap can help on those hard-to-get-out stains. Ask people with young children where they get theirs (it is a fair bet they deal with poo and other stains on the regular).

Secondly, use enzyme-cleaner. Some carpet-cleaner-products claim to have those enzymes, but I have found products such as "urine off" are much much more effective. Remember to treat at least double the area, because urine will spread a lot and you need this product to cover at least the same area. This will take care of any lingering smells - even to the point where the dog wont notice the smell.

For about 10+ years I've been cleaning a dog-school where puppies may have accidents, using a black-light to make sure I've gotten it all (and a dog to double-check and supervise). If it glows in UVA-light, it needs more cleaning. If the dog says so, it needs more cleaning. Repeat procedure.

This works. Some nurses found it hysterically funny that our cleaning-routine meant our place was cleaner than a hospital room.

Candles can't dehumidify a room because they burn hydrocarbons and produce moisture when you light them. If a candle were to reduce mold, it would be because it burnt something toxic to the mold.

And radiators dont cause mold? The heat and moisture may give the mold perfect growing conditions, but the moisture is what you want to get rid of. Use vents, fans, open a window, air out the house, use a dehumidifier.

Burning a candle to prevent mold is a shitty tip.
