Household oils, mechanical oils, greases and solvents can cause serious damage on your rubber gear!
Extreme heat will melt the latex. (Radiators, candles etc.). Long sunlight light will discolour your rubber, keep your rubber gear in the dark places.
Keep your rubber dry and give it enough time after you washed it. Metal will stain the rubber, avoid spots and discoloration. Sharp objects including long fingernails can easy cause holes or rip your latex garment. Just be careful when you put on your clothing. Sweat will damage your rubber in the long run! obviously nobody can avoid it, but remember to wash it off.
Fill your bathtub, a bucket or whatever you got with some hand warm water, add a few drops of Rubber Wash and wash your rubber! Then put it on a hanger and let it dry, in-and outside!
